Yashica Mat-124 G 120 / medium format camera

Yashica Mat-124 G, a medium-format twin-lens reflex film camera, with a waist-level viewfinder
film formats 120 and 220, produced by Yashica between 1970 and 1986.
Yashica Mat-124 G is the last model of twin-lens reflex produced by the company.
Being a twin-lens reflex (in English TLR, acronym for Twin-Lens Reflex) it is a type of camera equipped with two lenses of the same focal length, one brighter for focusing and the other complete with shutter and diaphragm coaxial for the exposure. Both are connected to the moving front, which advances or retracts according to the focusing wheel: what is shown by the first, on the matte glass of the waist-level viewfinder, is captured exactly on the frame.
