When the LEICA M celebrated its 40th anniversary, in the time spanning 1954 to 1994, LEICA M increasingly gained in importance and worldwide interest as the unique precision rangefinder system camera with timeless, elegant LEICA design. In commemoration of the anniversary of this classic camera, LEICA Camera Gmbh released 1640 special edition sets in which 40 years of LEICA M history with the special serial numbers 1954-01 to 1994-40. The first camera with the special serial number 1954-00 has since been preserved in the historical museum of Leica Camera Gmbh, Solms. The LEICA M6J is equipped with the ELMAR-M f/2.8/50mm with collapsible lens barrel. Camera and lens bear the same serial number. Included in the set is also a nostalgically styled leather ever-ready case. The set is supplied as a unit in a wooden case.
The LEICA M6J is a hybrid of the M3 and the M6 with the frame lines for 35mm, 50mm, 90mm and 135mm lenses. Unlike the LEICA M3, the M6J has TTL metering, hot shoe, motor drive connection, a M4 style rewind crank and a M6 battery chamber. With a 0.85 magnification finder, the M6J provides almost the same focussing accuracy with the 35mm frameline (not in M3).
I acquired this set in 1997 and it is still sitting in my dry cabinet.
