If it's not long enough, they never should have made one for the >"M"! I cannot remember if the 1.5 magnification is in the IIIa. Well, no. The LTM cameras had a 38mm baseline with a magnification of 1.5X, so the effective distance was 57mm. The Leica IV -- the prototype for the M cameras -- had a 60mm baseline with a magnification of 0.9X, for an effective baseline of 54mm. All of the M's have a real baseline of 69.25mm; with the various magnifications used, the effective baselines are between 49.86mm and 63.71mm. The real winner was the early Contax I, with an effective baseline of 92.7mm. I am still seeking the dispositive figures for the Retina, Ektra, and Prominent.
