What's the difference between a full-frame camera and APS-C format?
In digital cameras, all the 35mm films that will be used in 135 cameras are called full-width.
when it comes to APS-C, you have to talk about APS, advanced imaging technology. Advanced Photographic System (APS) is the specification of a new generation photographic system which is different from the 35mm film system, which was introduced by Kodak, Fuji, Canon, Minolta and Nikon in 1996.
The advanced photography system adopts 24mm film, with the negative area of 16.7 mm x 3.2 mm. The film adopts a cassette that can dorp-in, eliminating the need for manual winding. The cassette of advanced photography system marks the state of film, which has four States: unexposed, partially exposed, fully exposed and developed. Support to take it out in the middle of shooting and put it in again. Advanced photography system supports Information Exchange system. Film not only records image information, but also records exposure settings, and the developing system can adjust according to this information. When shooting, photographers can set three kinds of frame settings: standard (C 2:3), high-definition TV (H 9:16) and panorama (P 1:3). This setting will also be stored in the film, and photos with 4*6, 4*7 and 4*11 can be developed automatically when developing. After the film is developed, it will be returned to the box, which is convenient for the storage of the film. When the film is developed again, the photo number can be told to the development shop (the photo number can be obtained from the index film, and the photo number is also printed on the back of the photo)
APS is called the advanced photo system, which is a new type of film after 135, but its life is short. Due to the appearance of digital cameras, it was quickly eliminated.
the full size of p>APS film is 3.3×16.6mm ..
the negative size of ordinary 135 photos is 36×24mm.
APS film has three sizes, c, h and p. H-type is a full frame (3.3× 16.6 mm), C-type is to block one end at the left and right ends of the full frame, with an aspect ratio of 3:2, and P-type is to block one at the upper and lower sides of the full frame, with an aspect ratio of 3:1, which is called panoramic mode. DSLR borrows this standard, and calls both 22.5 x 15. mm and 23.6 x 15.8 mm, which are close to the size of C, APS-C frames. 28.7 x 19.1 mm is probably called APS-H frame.
