The Leica M6, as a rangefinder 135 camera worthy of professional photographers' trust and amateur players' dreams, features a robust body, reliable performance, durability, and simple functionality. It is said that before each batch of products is released, the Leica company will randomly select one M6 sample for a 100,000 shutter release test. If any faults occur during inspection or if the accuracy of the shutter speed decreases after 100,000 releases, this batch of products will not be allowed to leave the factory.
