What is medium shot kamera?

Answer 1

There are "miniature," "medium format" and "large format" cameras.

A miniature camera uses 35mm roll film.

A large format camera uses cut sheets of film. There are many sizes of sheet film but the most popular is 4" x 5".

Medium format cameras use roll film that's between 35mm and 4 inches wide. Today, the only size sold by film manufacturers is 2.25" (approx. 6 centimeters) wide and is available in two lengths: 120 and 220. A roll of 220 will hold twice the number of exposures as a roll of 120, but there are a LOT of problems with 220 so it never got popular. News photographers were about the only people who liked it, but a roll of 220 was more than twice as expensive as a roll of 120 so most guys figured, "if a roll of 220 is 2.5x the price of a roll of 120 and gives 2x the pictures, I'll just buy two rolls of 120 and save money."

The medium format shooters who really needed long rolls of film went right past 220 to 70mm. There were two ways to shoot 70mm: a back that held 15 feet of film and gave 70 square shots (the 70mm back for a Hasselblad is bigger, heavier and more expensive than a Hasselblad body), and a back that held 100 feet of film. The most popular camera using 100-foot rolls of 70mm was called a Camerz, and it was used in high-volume portraiture - school photographers, mall photo studios and the like.
