Leica M6 TTL
M-Mount The Leica M6 TTL is a 35mm film rangefinder camera manufactured from 1998 to 2002. As the direct successor to the "Classic" M6, it introduced Through-The-Lens (TTL) flash metering, a larger and ergonomically reversed shutter speed dial, and an upgraded 3-LED light meter display. It was the first Leica M camera to offer three distinct viewfinder magnifications (0.58x, 0.72x, and 0.85x) to suit different lens preferences.
