They differ primarily in their outer cosmetic plastic body panels, lens mounts and nameplates. This chassis is also used, in heavily reworked form, as the basis for the recent Rollei 35RF, Zeiss Ikon and Cosina's own Voigtländer branded Bessa R series of 35 mm film rangefinder (RF) cameras as well as the unique Epson R-D1 digital rangefinder camera in magnesium alloy."


Not sure if it is accurate, since wiki is prone to inaccuracies because anyone can write on it.
ah so i guess you are right. i thought the FM10 was rather flimsy when i handled it but the zeiss ikon is reported to feel solid and smooth in operation.
