Leica M6 TTL
A mechanical rangefinder camera with TTL flash control and an LED metering display.
Overview
The Leica M6 TTL is a rangefinder camera made by Leica. It is the brand's most advanced mechanical camera. It builds on the M6 with better flash metering and a refined viewfinder display. Metering is through-the-lens (TTL) and manual, with a set of LEDs in the finder showing exposure. The big upgrade over the standard M6 is TTL off-the-film flash exposure control. The M6 TTL takes every Leica M lens ever made, and Leica screw-mount lenses work with a simple adapter.

Design
The hot shoe has four central contacts to carry the TTL flash signals. The single-contact M6 has one, so the two are easy to tell apart. The viewfinder has four LEDs - three for manual metering and one flash ready/bolt indicator. The shutter speed dial turns in the direction the meter LEDs indicate, and it is shaped so you can adjust it with the camera at your eye. The mechanical shutter is rubberized for quiet operation.
