At least for my M6 Classic(any anyone elses) 57 vs 49 is longer in my book. - -----Original Message----- From: Marc James Small [mailto:msmall@roanoke.infi.net] Sent: Friday, October 01, 1999 10:34 AM To: leica-users@mejac.palo-alto.ca.us Subject: [Leica] Rangefinder Baseline At 08:29 AM 10/1/1999 -0500, Greg.Chappell@bankofamerica.com wrote: >I believe with the 1.5 magnification in the IIIf and IIIc rangefinder it's >effective rangefinder base is actually LONGER than an M2, M4, M5, M6 >Classic. 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.
