Leica M6 TTL
A mechanical rangefinder camera with TTL flash control and an advanced LED metering display.
Overview
The Leica M6 TTL is a rangefinder camera produced by Leica, recognized as the brand's most advanced mechanical camera. It builds on the M6 platform with enhanced flash metering capabilities and a refined viewfinder display. The camera features through-the-lens (TTL) manual light metering, using a system of LEDs visible in the finder to indicate exposure settings. It supports TTL off-the-film flash exposure control, a key upgrade over the standard M6. The M6 TTL is fully compatible with all Leica M lenses ever made and can work with Leica screw-mount lenses via a simple adapter.

Design
The Leica M6 TTL features a refined hot shoe with four central contacts to support TTL flash communication, distinguishing it visually and functionally from the single-contact M6. Its viewfinder includes four LEDs—three for manual metering guidance and one dedicated flash ready/bolt indicator—providing clear exposure feedback. The shutter speed dial is designed for intuitive operation, turning in the direction indicated by the meter LEDs and shaped for easy adjustment even with the camera at the eye. The mechanical shutter is rubberized for quiet operation, maintaining the tactile precision expected of Leica’s mechanical rangefinders.
