Mobile phone photography is so awesome, why do we need SLR cameras?

one is the image quality. The image quality is determined by pixels per inch. The sensor area of the mobile phone is so small (smaller than the small fingernail) that it can't be compared with the SLR (including the micro-single with the same specification) (24*36 16*24) under the same pixel condition. The so-called low child is crushed to death. This, especially under the condition of high sensitivity, their image quality is a world of difference. The second is the influence of depth of field. Because of the small area (foundation) of the mobile phone sensor, its focal length (actual focal length) is particularly small (generally 6mm), so it is difficult to shoot the depth of field effect (solid foreground, blurred background, etc.). Because of the large foundation of SLR, the actual focal length is the actual focal length, which can shoot the depth of field effect, even fantastic effect, and the effect is diverse. Third, the SLR lens group is rich. A SLR can use a lens group of about 1-8mm (Canon, Nikon), and a mobile phone cannot replace the lens. Fourth, the accessories are different. As far as flash is concerned, SLR can create many artistic lighting effects by off-board flashing. No cell phone. The fifth is the starting speed of the machine. The SLR starts up very quickly, so you can shoot when you raise your hand. It takes a few seconds for the mobile phone to start.

in a word, SLR is born for photography, and mobile phone is born for communication (photography is just recording), and the two directions are different. SLR communication is very simple, add a communication module, and the Android system will be ok. If the mobile phone wants to increase the sensor area, it will be in trouble. Followed by the lens, just look at the Sony micro-single. It is Quan Huafu (24*36), which lens is not small, and the large aperture head is even bigger than a SLR! The two can coexist in different development directions and learn from each other. However, at present, there is no problem of substitution in the future.
