The very last twin lens reflex ever produced by Yashica, and the most advanced. Designed as a Rolleiflex copy, the Mat-124 G features a four-element, 80mm f/3.5 lens set of the better "Yashinon" variety, shutter speeds from 1-second to 1/500th, an aperture range of f/3.5 - f/32, a bright ground-glass viewing screen, a crank arm film advance, and ergonomic aperture/shutter controls.
