there is no "true normal", normal is not an exact defintion of a focal length, and 50mm was what came with many many slrs for many years, one could argue that that was "normal", not 43mm or 55mm on film -- J.C.

O'Connell (mailto:hifis...@gate.net) 28mm is a 42mm-e on APS-C, pretty much exactly the same as Pentax's 43mm 'true normal' and right on the 40-45mm normal range that was typical for fixed-lens RF's and P&S's back in the day as well as being moderately common in SLR's from the mid-70's on. A 35 is a long normal on APS-C. 55mm as a normal was only ever an abberation of 60's SLR designs, as it was a bit easier to design for a SLR mount than 50mm that had been the the 'normal' for 35mm since the original Leica was introduced in the late 1920's. Many systems never even had a 55 normal or only had exotic 55's (usually an f1.2 or a macro). 55's as the standard on SLR's only lasted about 15 years from the early 60's to the late 70's, which was also when 40's and 45's became increasingly common as normals from Leica, Minolta, Nikon, Zeiss (Contax) Olympus and Pentax. Canon, Olympus and Nikon only did exotic 55's. 35mm has traditionally had a longer normal than other formats, due to Oskar Barnack's taste in lenses. -- M.
