Today's mobile phones have higher pixels than SLR cameras. Why can't they replace professional cameras?

Nowadays, the camera pixels of smart phones are getting higher and higher, and the photo taking effect is getting better and better. Many times, mobile phones can meet most of our photo needs. In fact, the camera function of mobile phone is Japan's J-Phone. In June 2000, it launched the world's first camera phone, with built-in1/kloc-0.0 million pixel CCD photosensitive element. The camera function of mobile phone is from birth to now. The world's first SLR was produced in 1884, and now it has been produced in 134.

In the era of functional mobile phones, it is discussed whether mobile phones can replace consumer cameras. In the era of smart phones, with more and more camera pixels, the functions of mobile phones are becoming more and more powerful, and the discussion about whether mobile phones can replace SLR cameras has begun. Some mobile phone manufacturers even advertised "killing SLR". Of course, this is just a gimmick of mobile phone manufacturers! Then, why can't the camera pixel be higher than the SLR camera? What's going on here?

First, high pixel does not mean good imaging quality: smartphone cameras have already entered the era of 10 million pixels, and 1300W pixel lenses have become very popular even on thousand-yuan machines. Some high-end models have reached 1600W and 2000W, and even Nokia has launched a 4 100W pixel mobile phone. It can be said that smart phones have surpassed SLR cameras in lens pixels. But high pixel does not mean high imaging quality, because imaging quality also includes photosensitive elements, software optimization and so on. Compared with SLR cameras, the size of the photosensitive elements of smart phones is much smaller, which is nothing compared with the APS-C format adopted by SLR cameras and even Quan Huafu. When shooting in low light and high sensitivity, the smart phone with a small bottom will have obvious noise. This is the main reason why it is difficult for smartphones to shoot at night.

Second, the speed of the SLR camera is fast: the shutter of the SLR camera is a mechanical shutter, and it can be imaged immediately after pressing the shutter, with almost no lag time, so the continuous shooting speed is also fast, and the start-up speed of the SLR itself is only a few hundred milliseconds.

Third, the mobile phone can't provide RAW files: When I want to keep the original environment when shooting, the mobile phone can't provide RAW files.

Fourth, it is easy to view and change the lens: SLR cameras view through the lens, so the picture the user sees is the picture to be shot, which is easier to observe when focusing; Moreover, SLR cameras can also be replaced at any time according to the shooting theme, which makes it easier to meet diverse shooting needs.

Fifth, the difference of zoom: Although the zoom of smart phones is all optical zoom now, further zoom is digital zoom, which will lead to poor image quality, but in fact, SLR cameras are stronger and can be further zoomed.

Therefore, from the overall and professional point of view, no matter how high the camera pixels of mobile phones are, they can't replace SLR cameras. what do you think?
