In today’s time, even cheap smartphones are coming with amazing features. There is a large battery, a good screen, and processors are also being sunk. But there is also a trend that is called multiple camera setup. That is, there is more than one camera sensor on the back of the phone. Now it has become difficult to find such a phone which has only one camera on the back. But you will ask what is the problem? The more cameras, the better for the customer, isn’t it? But this does not happen.
In many phones, extra camera lenses are put just to name. So that you look and say, “Hey this phone has four cameras, what would you do with a phone with three cameras or two cameras?” But to show ivory and eat more. The reality is that a phone with four lenses has only one working lens.
What is the benefit of multiple cameras?
Professional cameras have different types of lenses. Some have to zoom in, some focus on the nearest thing and some fill more scenes in the frame. The game of multiple camera setup was started to give the same things to the smartphone.
A depth sensor is usually seen with the main or primary camera sensor. What does it do? It blurs the background so that portrait pictures like DSLR are clicked from the smartphone itself. There is also a sensor called ToF or Time of Flight to do the same job even better. There is an ultra-angle lens which fills more scene frame than normal lens. There are two pictures below. One with a normal lens and the other with an ultra-angle lens. There is a telephoto lens that gives optical zoom to the phone. This means that you can zoom without losing the quality of the picture and click on the photo. Since last year, periscope style lenses have also started coming. They work exactly like binoculars. In the phone, the lens is kept in raft. This helps to zoom from 5 times to 100 times. Just look at Samsung’s Galaxy S20 series which has one such lens. You can see the hybrid zoom in action in the tweet below. Nowadays macro lens is seen in almost every phone. Its job is to click very close to a small object and click a photo. With this, you can capture insect spiders and cloth threads in detail too.
Then where is the problem?
Multiple cameras are very amazing in theory. But the problem comes when this system is given in cheap phones. Good camera lenses are expensive. And expensive components cannot be installed to keep the price of the phone low. So, finally, we get a useful multiple camera setup.
The above macro, ultraviolet and portrait samples have been taken from Realme’s X2 Pro smartphone at Rs 30,000. And all of them are very good. But when this realme gives the same camera setup in a cheap phone, then they are of no use. Because 8-megapixel ultra-angle lens and 2-2 mega-pixel depth sensor or macro lens is equal or not.
Launched in early 2020, the Realme 6 smartphone had an 8MP ultraviolet-angle lens with a 64MP main camera, a 2MP black and white portrait lens, and a 2MP macro lens. Its ultraviolet lens was fine to some extent, but the performance of both the other lenses was quite poor. The same was the case with its Realme 3 Pro smartphone.
Recently, Reality has launched Narzo 20 series. There are also 2-2MP extra camera sensors. It remains to be seen whether these will be like Reality X2 Pro or just such shows.
The Vivo S1 smartphone had an 8MP ultraviolet lens and 2MP depth sensor with a 16MP main camera. Here the depth sensor was of little use, but in the clicked picture from the ultraviolet sensor, the colors were neither good nor the details. The Poco X2 smartphone had an 8MP ultraviolet lens with a 64MP primary camera and a 2-2 mega pixel macro and depth lens. Ultravide lens was quite good but macro lens was quite useless. It was neither able to focus properly nor was it bringing color properly. Samsung’s last year’s Galaxy M30 smartphone featured a 13MP main camera with a 5MP depth sensor and a 5MP ultraviolet lens. In this, you must have known what an ultra-angle lens would have done. Barring the main camera sensor, both were useless. Enough to write that the phone has three cameras. And this is the Samsung that holds the record of camera performance with the S-series and the Note-series.
Samsung has made so much Progesssive Improvement?
However, Samsung has made improvements in Galaxy M31, but still some of Samsung’s phones are being given such extra sensors which are not equal. Similarly, some phones of Motorola, Infinix, Oppo, Xiaomi and Honor also have useless extra camera lenses.
So are all cheap phone multiple cameras worthless?
No, it is not like that either. Some cheap phones also have good quality extra cameras. But it is not necessary that their remaining things such as processor and battery etc. are good. Meaning that to keep the price of the phone low, the companies have to do some work. If the camera is given well then the processor will become useless or the charging speed will have to be given. Take LG’s W30 smartphone only. It not only gave a good 16MP primary camera, but also gave a nice 12MP ultrawide lens. But its performance was neither good nor build quality.
Then why are 4-4 back cameras being provided?
This question is justified that when it is so difficult to give a good multiple camera system in a budget smartphone, then why are companies lying in the three-three, four-four cameras? The answer lies with you yourself.
