Will smartphones do away with cameras?



How many people do you see on the street with a special camera in their hands? Probably very few, especially since smartphones have begun to offer shooting quality at least comparable to a DSLR.

However, in terms of quality, despite the great strides made by Apple, Samsung, Xiaomi, Huawei, Vivo, Oppo, etc., the truth is that a good camera still outperforms any high-end smartphone. At least for a while!

Do smartphones have what it takes to complete the cameras?

Thus, Sony is no longer the only giant in the mobile technology world who believes that smartphones have what it takes to surpass the image quality of digital SLR cameras in the near future. After all, Judd Heap, VP of Camera Product Management at Qualcomm, seems to share a very similar sentiment. You know why?

Because the capabilities of sensors continue to grow, and in fact the level of development and innovation in this area is much higher than in the rest of the photographic industry.

What’s the secret?

S22 Ultra, Vivo, X80 Pro

Apparently, the potential lies in the level of processing that exists in the world of smartphones, especially in the higher ranges. After all, compared to the most powerful cameras on the shelves, be it Sony, Canon or Nikon, any high-end smartphone is at least 10 times more powerful in terms of processing power.

Computing power, which, as you understand, has only increased.

Big brands don’t want to fight smartphones.

As you may know, Canon has already announced the end of its DSLR lineup, and it looks like Nikon is joining the same train with its focus on mirrorless cameras.

In short, the greats of this world know that it is impossible to fight the practicality that smartphones offer.

So what about the megapixel war? This is an obstacle to evolution!

A Qualcomm expert believes that this new numbers war in the world of smartphones is useless, and that for a good development of the market, it would be a good idea to bet on sensors between 40 and 50MP.

A curious proposition, as Samsung will make a big and ugly 200MP bet from next year on its top of the range Galaxy S23 Ultra. Here we must take into account that more megapixels does not necessarily mean larger sensors. Pixels will be smaller, and for this reason, they may have difficulty getting light through. In the near future, it is very likely that the maximum sensor size for smartphones will not exceed one inch (1 inch).

Besides, what do you think of all this? Do you think that cameras will die, remaining only for professionals? Share your opinion with us in the comment box below.
