What's the difference between a half shot and a full shot?

1, Quan Huafu: refers to the specification with a photosensitive area of 36× 24 mm This specification is used to describe the imaging circle index of the lens and the size of the photosensitive element.

2. Half frame: also called APS frame, refers to the imaging area based on "APS system".

Second, the classification is different.

1, Quan Huafu: In the charge coupled device sensor technology, the content of the sensor covers the whole photosensitive element area, instead of sharing it with related pixels in the same space.

2. Half frame: APS film has three sizes: C, H and P. The H type is Quan Huafu (30.3× 16.6mm) and the aspect ratio is 16:9. The C type is blocked at the left and right ends of Quan Huafu to make the aspect ratio 3:2, and the P type is blocked at the upper and lower sides of Quan Huafu to make the aspect ratio 3:/.

Due to the widespread use of 35mm film, 36×24mm has become a specification. Under this specification, 35mm has become a standard for us to judge the lens angle. For example, 28mm lens can achieve wide angle, 35mm is the standard angle of view, 50mm is closer to the human eye angle and so on.

However, in the digital age, the photoreceptors used in digital SLR cameras are more than 36×24mm, so there is a problem of magnification. For example, APS-C size, magnification 1.5 (Canon1.6); 4/3 system, magnification 2; Sigma X3 system, magnification1.7; Canon APS-H size; The magnification is 1.3, etc.
