I can believe that, as there's a little bit of play between the focusing ring and the parts that move the lenses. But it really shouldn't make any difference at all to the result, as the wheel which goes against the cam is spring loaded. (And logically the same applies not only to range finders, but to SLRs as well.) If it does make a difference to the photos, then I'd guess the problem is with the lens, as there shouldn't be any significant front and rear play between the cam and moving lenses. - -- Urban Fredriksson griffon@canit.se http://www.canit.se/%7Egriffon/ My photo pages: http://www.geocities.com/Athens/Olympus/1568/pix.html
