If you have a full-frame camera, why do you have a medium-frame camera? Is there a market for medium format cameras? It is estimated that few people or companies use Chinese format.

Quan Huafu is equal to 135 film and medium format is equal to 120 film, so the area of medium format is larger than that of Quan Huafu. At present, due to the high price of medium format camera, it can not be popularized to ordinary lovers only in professional fields for the time being, but with the gradual maturity of photosensitive element technology, its price will soon be popularized to ordinary people.

First, you have to know what the camera border is. The frame refers to the photosensitive area. Based on 35 film areas, a digital camera is equivalent to 35 film areas called Quan Huafu. In APS system, the area of C frame is about half that of Quan Huafu, so it is also called half frame or residual frame. 1/2.3,11.8 ...1inch, etc. Represents the photosensitive area of 1/xx inches. The film area equivalent to 120 is called medium format, and the film area larger than medium format is called large format, but there is no digital photosensitive element in large format, only film.

The frame is the size of the photosensitive element. Under the same picture quality, the larger the frame, the higher the pixels that can be analyzed, and the larger the pixels, the larger the format that can be printed. The diffusion circle spreads outward from the center, and the bigger the picture, the more vivid it is. Some photographic creations need not only medium format but also large format film.
