What's the difference between a mobile phone camera and a SLR camera?

There is no difference between pixels, pixels are just an indicator to measure the quality of photos.

Now the pixel of mobile phone camera is advancing by leaps and bounds. If the Nokia mobile phone has more than 40 million pixels, you should know that the average SLR has only100000 to 20 million pixels, and the D800 has 36 million pixels, which is relatively high. But the photography ability of this Nokia phone will never be as good as that of the D800.

Pixel only refers to the resolution of the photosensitive chip of this camera (camera), and how many points will be used to represent a picture (for example, for a camera with14.2 million pixels, there are14.2 million points to represent a picture, that is, there are 4608X3072 matrix points to represent a picture, and the picture ratio is 3: 2). But whether these points can be sensitized well, completely and correctly is the key point. The most important thing is whether the photographed objects and light and shadow can be fully displayed.

In fact, if you look at more information, you will know that the shooting ability of the camera is mainly determined by the size of the photosensitive chip inside the camera and the advanced technology. Generally speaking, the grade of the camera can be basically divided by the size of the photosensitive chip. For example, a full-frame camera is more expensive than a half-frame camera, a half-frame camera is more expensive than a card machine (the photosensitive chip is smaller and different), and a card machine is more expensive than a mobile phone camera (not necessarily). Of course, these are general rules, which will be different because of the influence of brand and other conditions. For example, some half-frame cameras are more expensive than those in Quan Huafu.

Compared with professional cameras, first of all, the photosensitive chip is much smaller, perhaps only one-tenth to one-tenth of that of professional cameras. Two chips with such a big difference should integrate more than 654.38+million pixels, and the area of the photosensitive chip shared by each pixel is quite different, so the effect of photosensitive imaging is of course different.

The second is the ability of the lens. I don't need to say who is more capable between mobile phone lens and professional camera lens.

And the ability to shoot in bad conditions (such as darkness, or shooting fast-moving objects, etc. ) Not as good as a professional camera.

So there are many factors that affect the quality of photos, and the resolution is only the basic index. What really affects is the ability of the camera's photosensitive chip and the various capabilities of the fuselage (such as processor capability and high sensitivity). ), the quality of the lens (the lens is also very important), and of course the ability of the photographer.

On the other hand, if you are shooting in a good place, the mobile phone is not a problem. Suitable for taking photos of this trip. After all, it is light and multifunctional.

If you really like photography, of course you want a SLR camera.
