Dual phone. History of dual camera phones

A dual camera is a very interesting trend in the mobile industry, which for some reason is ignored by market giants like Samsung and Sony. The gadgets from this guide are equipped with screens with a diagonal of 5.1 to 6.4 inches (at least with Full HD resolution), batteries with a capacity of 2500 to 5000 mAh, 2–4 GB of RAM and 16–256 GB of internal memory, support LTE-A. The review focuses on dual cameras, the resolution of one of which is ≥12 megapixels.

Apple iPhone 7 Plus

Let's start with a larger version of the latest smartphone Apple, featuring a dual 12-megapixel camera. The main lens is wide-angle - 28 mm (equivalent) - with aperture F1.8. The second is both portrait and zoom with 2x magnification, its focal length is 56 mm (equiv.), and its aperture is F2.8. The first camera block features optical image stabilization. In addition to standard shooting modes, the iPhone 7 Plus has a Portrait mode with a shallow depth of field. You can take photos at 2x zoom, adjust shooting settings manually, and shoot in RAW format(using third party applications). Read more about the photographic capabilities of the smartphone in our review. Among other characteristics of the flagship: the first in iPhone history quad-core Apple A10 processor, 3 GB random access memory(instead of 2 in the usual “seven”) and a drive with a capacity of 32, 128 or 256 GB. We also note the magnificent 5.5-inch display.

ASUS Zenfone 3 Zoom

Zenfone 3 Zoom was presented in the first days of this year, focusing on the model’s extensive photographic capabilities. With a quite reasonable price tag, the smartphone has a 13-megapixel front camera and a rear camera with two IMX362 sensors from Sony, 12 megapixels each. The main camera is equipped with a 2.3x optical zoom, triple autofocus, F1.7 aperture, a hybrid image stabilization system and support for video shooting in 4K resolution. Inside there is an eight-core Qualcomm Snapdragon 625 MSM8953 processor with an Adreno 506 graphics accelerator, 4 GB of RAM, 64 GB file storage expandable with microSD cards up to 2 TB and a huge 5000 mAh battery.

Honor 8

This is one of best smartphones last year in terms of price and quality ratio. He collected an incredible amount of flattering reviews from both ordinary users, and from leading IT specialists. All thanks to amazing optimization, very smooth and stable operation, combined with excellent characteristics and an attractive price. There is a good 8-megapixel front camera here. The main camera consists of two 12 megapixel modules with laser autofocus and F2.2 aperture. We have already evaluated the performance of the cameras, the test results are on this page. The smartphone has a bright Full HD display with a diagonal of 5.2 inches, powerful processor HiSilicon Kirin 950 and 4 GB of RAM. Among the others Honor benefits 8 - a high-quality body made of plastic and metal, 32 GB of built-in expandable memory and a fast fingerprint scanner.

We also note the Pro version of the device, which is also equipped with a dual camera. Honor 8 Pro is a smartphone with a large diagonal of 5.7 inches. It just appeared on the market, but we have already tested it.

Huawei P10

Many believe that the Huawei P10 is just a slightly modified version of the previous P9 model. However, the new product is a much more modern and advanced product. While the predecessor used two 12 MP photo modules, the P10’s Leica Dual Camera 2.0 consists of two sensors with a resolution of 12 (color) and 20 MP (monochrome). The Leica Summarit-H F2.2 lens is fast, its focal length is 27 mm (equivalent). The remaining characteristics of the flagship are also “pumped up”: the device is built on the basis of an eight-core HiSilicon Kirin 960 processor (vs. Kirin 955 in previous version), the amount of RAM has increased from 3 to 4 GB, the capacity of the non-removable battery has increased from 3000 to 3200 mAh, the OS has been updated: from Android 6.0 to Android 7.0.

Speaking about Huawei P10, it is worth mentioning the P10 Plus model. It has a 5.5-inch Quad HD display (instead of 5.1" in the regular P10), so the smartphone can be recommended to lovers of large screens and fans of night photography. There is the same 12+20 megapixel main camera, but different optics are used - Leica Summilux-H - with a higher aperture of F1.8.

LG G6

LG G6 is the new flagship of the Korean company. The gadget was first shown at the Mobile World Congrees 2017 exhibition in Barcelona, ​​where it was quite warmly received by journalists and highly appreciated by engineers from other companies. It is notable for its almost frameless, dust- and moisture-proof glass and metal body and excellent dual main camera. Like the ex-flagship LG G5SE, it consists of two 13 megapixel photo modules, one of which is wide-angle (equivalent focal length - 29 mm) with a viewing angle of 71 degrees, and the second ultra-wide-angle - about 12 mm (equivalent), angle review - 125 degrees. LG G6 is also equipped with a high-quality 5.7-inch screen with a resolution of 1440x2880 pixels and an aspect ratio of 18:9 (or 2:1), Qualcomm Snapdragon 821 chipset, current version Android 7.0 Nougat OS, 4 GB of RAM, 64 GB storage, 5-megapixel front camera with F2.2 aperture and 100-degree viewing angle, as well as a non-removable 3300 mAh battery with technology support fast charging QuickCharge 3.0.

LG X Cam

Despite the relatively affordable price, the X Cam has a dual main camera, consisting of a standard 13-megapixel and a 5-megapixel wide-angle module with a viewing angle of 120 degrees. The LG X Cam, although not particularly exciting, is completely worth its price. This is thanks to the front camera with a resolution of 8 megapixels, a 2520 mAh battery, an eight-core MediaTek MT6753 processor with a frequency of 1.1 GHz, 2 GB of RAM and 16 GB file storage, the volume of which can be increased to 2 TB via microSD cards.

Xiaomi mi5S Plus

This smartphone has a stylish metal body, a Snapdragon 821 chipset with a frequency of 2.35 GHz, a spacious 64 GB drive and 4 GB of RAM (in a more advanced version, these figures are 128 and 6 GB, respectively), a large battery with a capacity of 3800 mAh, USB connector Type-C, a fingerprint sensor, a 4 megapixel front camera and a dual main camera with 13 megapixel sensors (the technology here is similar to that used by Huawei: a combination of black and white and color photo modules).

Lenovo Phab 2 Plus

If Xiaomi is just beginning to integrate dual cameras into its smartphones, then another Chinese manufacturer Lenovo has already accumulated experience in using two photo modules in one device. The company has combined two original solutions in Phab 2 Plus: a huge 6.4-inch screen with Full HD resolution and a 13-megapixel main camera with laser autofocus and an F2.0 lens. The hardware of this phablet allows you to solve most everyday work and multimedia tasks. It runs on an eight-core MediaTek MT8783 processor with a frequency of 1.3 GHz, the amount of RAM and internal memory is 3 and 32 GB, respectively, and the battery capacity is 4050 mAh.

ZTE Blade V8

ZTE engineers placed modules in a double camera, one of which has the usual 13 megapixel resolution, and the second - only 2 megapixels. However, such a combination is enough for post-focusing and creating 3D photographs. Costing just over $300, the Blade V8 runs state-of-the-art operating system Android 7.0 out of the box, equipped with an ergonomic body made of aircraft aluminum, a bright Full HD screen with a diagonal of 5.2 inches, a powerful eight-core Qualcomm Snapdragon 435 processor with an Adreno 505 graphics accelerator, 2 GB of RAM, 16 GB of storage (+microSD up to 128 GB), a high-quality 13-megapixel front camera and a battery with a capacity of 2730 mAh.

The iPhone 7 Plus uses two cameras with a resolution of 12 megapixels. One module is wide-angle, it allows you to capture more light and take high-quality pictures even in low light conditions, and the second is telescopic, thanks to which a 2x optical zoom is realized. So you can take closer shots and zoom in without losing quality if the subject is far away.

The smartphone also uses Portrait mode, which allows you to keep the foreground in focus and blur the background. The result is beautiful and expressive portrait photographs comparable to the quality of SLR cameras.

In addition to two cameras, iPhone 7 Plus has a 5.5-inch screen with Full resolution HD, the most powerful Apple A10 Fusion processor and stereo speakers. All this is enclosed in a thin metal case, protected from water and dust according to the IP67 standard.

Operating system: iOS 10. Processor: Apple A10. RAM: 3 GB

Huawei P10

Huawei was one of the first to produce smartphones with two cameras, promoting this feature as a key one. Last year the very successful P9 was released, and in 2017 its successor, the Huawei P10, went on sale.

The new product features two camera modules developed jointly with the German company Leica. The first module is color at 12 megapixels, the second is monochrome with a resolution of 20 megapixels. Automation instantly combines images from two cameras, producing beautiful images with a wide dynamic range and excellent color rendition.

Dual-camera technology is also used for the bokeh effect - a beautiful blur of the background. The device can also photograph distant objects without loss of quality - for this, a 2x hybrid zoom is used. We haven’t forgotten about optical stabilization, which prevents you from taking a blurry picture even in poor lighting.

The remaining characteristics are as follows: a 5.1-inch display with Full HD resolution, 4 GB of RAM and 32 GB of internal memory, expandable with a memory card, an eight-core Kirin 960 processor and a 3200 mAh battery that supports fast charging using Huawei’s proprietary SuperCharge technology.

Honor 8

Another smartphone from the company with two cameras. Both modules have a resolution of 12 megapixels. One lens takes a black and white image, and the other takes a color image. The two frames are then merged almost instantly. This is necessary to expand the dynamic range - the ability to preserve details in the darkest and lightest areas of the frame.

The camera uses a wide aperture mode to blur the background. Using this function, you can manually adjust the depth of field during shooting or after the shot is taken.

In addition, when editing a photo, you can change the focus points, bringing the desired subject to the foreground. In general, the camera in Honor 8 gives its owner ample opportunities for creativity.

Honor 8 also boasts a beautiful glass body and a large number of colors - blue, black, white, pink and gold. The smartphone is powered by a powerful Kirin 950 processor and 4 GB of RAM. There are two options to choose from - with 32 or 64 GB of internal storage. The battery capacity is 3000 mAh, and the screen is a 5.2-inch IPS matrix with Full HD resolution.

Xiaomi Mi5s Plus

Xiaomi Mi5s Plus is equipped with a dual main camera with a resolution of 13 MP + 13 MP. One module takes a color photo, and the second takes a monochrome photo. The main feature of the camera is that the two modules do not work together by default - to do this, you need to activate a special stereo mode by selecting the aperture icon on the display.

The camera in this mode becomes noticeably slower, but allows you to take pictures with a wider dynamic range and better detail in the dark.

The characteristics of the smartphone are as follows: a 5.7-inch Full HD screen, a Qualcomm Snapdragon 821 processor, 4 GB of RAM, 64 GB of internal memory and a 3800 mAh battery. As a result, we get a large flagship at an attractive price.

LG G5 SE

LG also uses dual cameras in many of its smartphones, but their functionality is completely different from what other manufacturers use. The main module of the G5 SE has a resolution of 16 megapixels, the second is a wide-angle 8-megapixel module with a shooting angle of 135°.

A separate wide-angle lens, as conceived by the creators, should help photograph panoramic landscapes, tall buildings or groups of people without the need to move a long distance from the subject.

Switching modes occurs instantly; for this, the camera interface has two corresponding buttons. According to LG research, users of this smartphone They use wide-angle shooting in 55% of cases - this indicates that the function is in great demand.

The LG G5 SE was equipped with a 5.3-inch screen with a resolution of 2560x1440 pixels and the Always On Display function, a Qualcomm Snapdragon 652 processor, as well as 3 GB of RAM and 32 GB of internal memory, and a 2800 mAh battery.

In addition, the smartphone is made using a unique modular system. Instead of a removable bottom panel, you can install various branded modules. For example, a handle with an additional battery and camera control buttons or a module with a digital-to-analog converter for music lovers, developed jointly with the Danish company Bang&Olufsen.

Asus Zenfone 3 Zoom ZE553KL

Asus presented the Zenfone 3 Zoom at CES 2017 and is already available for purchase in Russia. The main feature of the smartphone is its dual camera module.

The main one has a wide-angle lens with a large aperture (f/1.7) and a 12 megapixel matrix with support for ASUS SuperPixel technology. It is designed for shooting everyday scenes, including in low light.

The second camera - with the same 12 megapixel resolution and 2.3 times optical zoom - is used to take high-quality close-up shots. That is, the key feature of the device is the 2.3x optical zoom, which allows you to zoom in without losing quality.

The camera is not the only advantage Asus Zenfone 3 Zoom. The new product has a 5000 mAh battery installed - it should be enough for a couple of days of active work.

The smartphone is powered by a Qualcomm Snapdragon 625 processor and 4 GB of RAM, which is enough to run all modern games without freezing. There is 64 GB of memory for data storage and the screen size is 5.5 inches. And all this at a very attractive price.

ZTE Blade V8

Phab 2 Pro is the world's first smartphone to support Tango, Google's technology that brings augmented reality (AR) to games and apps. The gadget has not two, but three modules located on the back - a main 16-megapixel camera, a depth camera and a motion tracking camera.

Thanks to the cameras, sensors listed above and the developed software The phone can create a 3D model of the room in which it is located. That is, the device is able to track movements, explore the environment and perceive the depth of space. This data is subsequently used to superimpose the virtual image onto the real world image displayed on the phone screen.

On this moment This is an experimental feature, but it already works great and has virtually no errors. But there is also a problem - there is practically no software for this technology yet. You'll have to make do with a few apps and a couple of games.

Lenovo Phab 2 Pro received good components. The device is powered by Qualcomm Snapdragon 652 processor with clock frequency 1.8 GHz. The Chinese also installed 4 GB of RAM and 64 GB internal memory(of course, it can be expanded). In addition, under the 6.4-inch Quad-HD display there is lithium ion battery at 4050 mAh.

Not long ago, Sony made a rather bold statement. According to the company, in 2017, flagship smartphones, the production of which Sony took up. You've probably heard that the iPhone 7 Plus is likely to have a dual camera setup. He won't be the first. Many flagship smartphones already delight users with a dual camera.

We will not remember LG Optimus 3D and HTC Evo 3D, which several years ago tried to surprise the owners of these smartphones with 3D photographs. It was a bad idea. Only after a while were manufacturers able to find a use for the dual camera module. Where is it already used? In these smartphones:

HTC One M8


The second camera on this HTC allows users to change the focal length of a photo they've already taken. It is noteworthy that already in the next generation of flagship HTC smartphones the second camera disappeared.

Honor 6 Plus


Huawei has found a completely different use for the dual camera. Two sensors allow the smartphone camera to receive more light and take better photos in low light. The smartphone software takes two photos from 8-megapixel cameras into one 13-megapixel photo.

Qiku Q Terra


The two 13-megapixel sensors of this little-known Chinese smartphone also allow you to take high-quality photos in low light.

Lenovo Vibe S1


In that Chinese smartphone two front cameras designed for selfies. The 8-megapixel front-facing camera does all the heavy lifting, while the secondary 2-megapixel camera is used for distance estimation, similar to the HTC One M8.

LG V10


This smartphone will offer you to take selfies in a group or alone. To ensure that your entire company is included in the photo, the smartphone is equipped with a wide-format 8-megapixel camera. The 5-megapixel camera is suitable for photographs of the owner alone.

LG G5


The new product from LG offers all the same things, but this time we are talking not about the front cameras, but about the main cameras. There is also a mode that allows you to use wide-format and regular cameras for one shot.

Based on materials from PhoneArena

Nowadays, phones with dual cameras are not uncommon. They can often be found on sale, but many people still do not understand why some manufacturers began to equip gadgets with such a function. Well, there is an explanation for this.

3D creation

This is the first thing dual camera phones were made for. Everyone remembers 2011 very well, when the craze for home 3D began. People began to actively buy televisions that supported stereo images. So smartphone manufacturers decided to keep up with fashion trends. Also in 2011, phones such as LG Optimus 3D and HTC EVO 3D were released. By the way, you can see them in the photo provided above.

The screens in them used a special parallax barrier. Due to this technology, a person’s left eye saw one part of the pixels, and the right eye saw another. Viewing 3D materials has become real. However, the two cameras worked the same way. The first lens saw one part of the pixels, and the second - another.

However, these dual camera phones did not become popular. They aroused interest, but buyers did not like the fact that the displays had a low resolution, which reduced the quality of the material being filmed. And smartphones turned out to be inconvenient to use. To take a 3D photo, you had to hold the phone motionless at one point - the slightest movement would ruin the frame.

Panoramic effect

When taking photographs, people always want the entire object they want to capture to be included in the frame. But this does not succeed in every case. Phone manufacturers are well aware of this fact. That's why dual camera phones have emerged, designed to expand the field of view of the lens.

Many will say: “But smartphones now have fisheye and panorama functions!” Yes, it is available. It’s just that such smartphones have universal optics, the viewing angle of which is limited. In order to get as much detail as possible into the lens, you have to use very curved lenses, or make photo sensors of a wide, non-standard format. The pictures turn out to be greatly reduced in height, and the quality also suffers.

But with a smartphone with a dual module you can take excellent photos. To do this, you just need to press the button once, fixing the desired object. You will get a great photo without gluing or graphic defects. A striking example such a phone is LG G5, costing 22-25 thousand rubles. One camera in the module has a viewing angle of 90 degrees. The other, highly specialized, is wider - 100-120.

Improving photo quality

This is another reason why we need dual cameras on phones. Single lens smartphones do not have optical zoom. If you need to bring an object closer, the system will simply take the required piece of the image and then “stretch” it. Naturally, there can be no talk of any detail. But a double module solves this problem. After all, it includes one regular camera and another telescopic one. The recently released iPhone 7 Plus boasts the presence of such a module. In it, both matrices are the same, but one is equipped with high-aperture optics with normal parameters, and the other has a long-range view with a limited viewing angle.

Increasing contrast, clarity and detail - this is another reason why you need a dual camera on your phone. A very useful feature. When a module has both color and monochrome cameras, this is reflected in the quality of shooting. One optic captures colors and shades, while the other registers the smallest details. The result is a bright, detailed picture. This is exactly the module installed on Huawei P9, the price of which is about 30,000 rubles.

Xiaomi Redmi Pro

I would like to pay special attention to this model phone. Mi 4 Pro with dual camera is very popular now. But Xiaomi was the last of those who decided to develop this concept.

The main camera of this model is 13 megapixel. The second is 5 megapixels. This is what captures the depth of the data. Thanks to its presence, Xiaomi Redmi Pro takes amazing pictures with a bokeh effect (the subject of the photo is in focus, and the background is blurred). Interestingly, the settings can be adjusted by the owner of the phone. The aperture is easily adjusted manually, thereby achieving the desired level of blur.

By the way, this phone has already been tested by many technology connoisseurs, and most of them did not forget to compare the Xiaomi Redmi Pro with the seventh iPhone. But really, photographs taken from the cameras of both models are no different. But Xiaomi costs as much as 1/3 of an Apple phone.

Cheap models

As you can already see, smartphones with such impressive optical characteristics are quite expensive. But, since models with such functionality soon became popular, manufacturers of budget smartphones quickly set up their production. Chinese phones with a dual camera - a good alternative to all the previously mentioned models.

Take, for example, Doogee Shoot 1. Its price varies from 5 to 6.5 thousand rubles. Its optical module consists of a 13-megapixel main camera made by Samsung, and a second additional one of 8 megapixels. Photos are bright, clear and detailed, and the notorious bokeh effect can also be achieved easily.

The Elephone Max, which is the company’s first experimental smartphone, costs a little more (6.5-7 thousand). The manufacturer interested buyers with a dual camera capable of taking pictures at the same level as DSLR cameras.

Third a budget option- this is LeEco Cool1, the price of which varies from 9 to 14 thousand (depending on the configuration). The module of this smartphone includes two 13-megapixel cameras, f/2.0 aperture, and dual led flash and phase detection autofocus. The most important thing is that this phone shoots video in 4K Ultra HD format. The front camera of this model, by the way, is 8-megapixel, and records videos in 1080p format.

Elite Chinese model

A much more expensive Chinese option is the Gionee M2017. It costs about 65-75 thousand rubles in its usual form. In China, versions in crocodile skin are still sold, and they cost a hundred thousand more.

The price is explained by the presence of an 8-core processor, an incredibly thin body, 64 built-in gigabytes of memory, a 2560x1440 display expansion and, of course, an optical module. It consists of 12 and 13 megapixel cameras respectively, which support 4x optical zoom. There is also a powerful LED flash.

Smartphones for selfie lovers

Gadgets with dual front cameras also exist! These are Vivo X9 and X9 Plus, released in December 2016. These smartphones have a regular 16-megapixel camera on the back. But in front there is a double front module. One camera is 20 MP and the other is 8 MP. And the aperture is f/2.0. This is a really great dual camera in a phone.

Why was it decided to install it specifically in the front part? Because such a solution is new to the gadget industry, and besides, selfie lovers want high-quality photos. And with such characteristics, even the bokeh effect can be created in one motion. During shooting, the main camera focuses on the person's face, and the other creates background blur.

The price of these models varies from 22 to 28, and from 30 to 35 thousand rubles, respectively.

Bluboo Dual

This is the last model that is worth noting. Its price starts from 5,700 rubles. The dual module consists of a main 13-megapixel Sony cameras IMX135 and from a 2 MP auxiliary sensor. Despite the fact that the characteristics are less impressive than all the previously mentioned models, it is possible to achieve beautiful background blur and clear focus with such a phone.

In general, as you can see, there are a considerable number of smartphones with modular cameras. If you wish, you can find a good gadget at a reasonable price, buy it and enjoy high-quality pictures.

As soon as there were rumors last year that Apple wanted to make a smartphone with two modules at once, manufacturers became seriously alarmed and began making two-eyed smartphones intermittently.

Some did well, some did poorly, and some were just disgusting. But what are the real advantages of a dual camera? How does it work, what does it give and what is better - a smartphone with one or two modules?

Principle of operation

A dual camera works exactly the same as a single camera. Light passes through the lens and hits the matrix, the processor reads the information from the sensor and converts it into a photo or video.

With dual cameras, everything is the same, only instead of one matrix there are two, which work independently of each other, which means that all processing and stitching of images takes place in the processor and the more advanced it is, the better the quality of the images will be.

For high-quality photos, software algorithms are also important, and what functions the second module has depends on what the manufacturer provides.

Optical zoom

For example, the second camera in the iPhone 7 Plus is designed for optical zoom. The first module shoots with a wide-angle lens, and the second telephoto lens allows you to take zoomed photos without losing quality.

Previously, zoom in smartphones was mostly digital, that is, the smartphone took a large 16 megapixel photo and cropped the necessary fragment programmatically (for example, 2 times) and the resulting photo was no longer 16 megapixels, but only 8 megapixels, and accordingly the quality was lost. Now the second module has an optical zoom, that is, a photo enlarged by 2 times is obtained without loss of quality. But not all manufacturers followed this path.

Increased dynamic range

Some people use the second module for other purposes. Like, for example, the dual camera in Huawei P20. It was created not for zoom, but to increase the dynamic range, and it is not capable of zoom. One module is regular, and the second is monochrome and shoots only in black and white. According to the developers, this gives more detail in the shadows, and the pictures themselves are of better quality, although only a professional can see the difference.

Improved detail

Manufacturers do not always insert the same matrices into both modules. More often, one module is made with fewer megapixels, but at the same time with greater aperture. And the second one has more megapixels, but less aperture.

By combining two such photographs you can get a more detailed picture. Because information about colors is taken from the first image, and information about details from the second.

Changing Focus

Also, some manufacturers use a second module to take pictures with variable focus. That is, first you took a photo, and then in the gallery you changed the focus point, if necessary.

And finally, any smartphone with a dual camera can blur the background, or rather create a depth of field effect (bokeh).

In fact, the blur occurs programmatically. The second camera is needed to more accurately determine the object in space. The processor takes two pictures on both cameras, compares them and determines which object you wanted to place in the foreground, after which it applies a filter in real time and blurs the background. In this case, you can often independently set the degree of background blur for the image. This is called program aperture. The wider the aperture is opened, the more the background will be blurred, but most likely more important details will disappear from the image and vice versa.

Software algorithms

When dealing with a dual camera, the software algorithms that process the image are very important. If the algorithms are correct and work without errors, then the background blur occurs correctly - the necessary objects are not erased, and the edges come out smooth.

At the moment, there is no camera that always and accurately determines where the object ends and the background begins.

The best smartphones with dual cameras

Here are a few smartphone models that take better photos with their dual cameras.

OnePlus 5
OnePlus 5 smartphone

Xiaomi Mi6
Smartphone Xiaomi Mi 6 4GB/64GB

Huawei P20

ZTE Nubia Z17
Smartphone ZTE Nubia Z17s 128GB

The photos they produce are of the highest quality. But latest model It’s not worth buying from the list yet, since the firmware is still raw, you need to wait until the fall. The iPhone 7 Plus is also known to blur the background quite well.

Our review included mainly expensive models; there are also cheaper options with two cameras – Doogee Shoot 2, Leagoo M8 Pro.

But you shouldn’t expect high-quality pictures from smartphones costing about $100; they don’t determine the position of the object, but simply “wash out” everything that is possible and impossible.

It is unlikely that you will be able to get a correct photo with such a smartphone. As practice shows, budget smartphones with a price of less than $150 cannot work properly with a dual camera and it’s not worth buying them just for this.

Cost of smartphones with dual cameras

All this is of course good, but how does the presence of a dual module affect the cost of a smartphone? Naturally, there are more components, assembly becomes more complicated, and the manufacturer needs to improve the software in order to adequately use the second module. And all this requires additional costs. However, in fact, devices with a dual camera and a single camera are almost the same in price. So, most likely, adding an additional module has little effect on the cost of the product and the price changes insignificantly.

Do you need a dual camera?

After weighing all the pros and cons, we can say that the presence of a dual camera is more of a plus than a disadvantage. Objectively, if it does not affect the price and brings additional benefits, then why not?

The most adequate option for using a second camera is optical zoom. We are all accustomed to the fact that a smartphone has a fixed viewing angle and in order to enlarge an object without losing quality, we must first approach it. The second telephoto lens solves this problem - I saw a beautiful frame, pressed the button, zoomed in and got a good shot. This is what makes life easier for a mobile photographer.

Plus, if you don't go overboard with the program aperture, you can get great shots, adding an artistic touch to your photos. That is why, when choosing a smartphone today, we prefer a device with two cameras rather than one. Because if you don’t want to, you don’t have to use the second module, but when you need a zoom it will always be at hand.

What to expect in the future

How will the industry develop further, where will the trends go and how will we be able to modify cameras in the future? What other uses for the double module could be found? In our opinion, progress will not stop with just two modules; there are already smartphones with three cameras.

Perhaps four modules with a resolution of 16 megapixels, connected into one conglomerate, will help in the future to obtain high-quality 40-megapixel images. Each camera will take a picture of its own area, after which the processor will “glue” them into one large canvas. Currently used for this panoramic mode in smartphones, but taking big pictures is still not that easy.
