This is my conclusion too. see my thread http://www.apug.org/forums/forum45/1...teresting.html where I did a little test. OK, a fairly grainy film/developer combination and yes, all at 250 F8 so stopped down, not wide open, but I half expected the 50mm MIJ Zuiko 1.8 to be the "best" (as it's a lens that has an excellent reputation), and in fact it was indistnguishable from the Schneider on the Retina and the Jupiter 8 Sonnar clone on the Kiev. the resolution disappeared into the film grain, and I don't believe any lens would have given a different result.I rented a bunch of premium lenses a while ago, Zeiss included, and maybe I'm crazy but I didn't notice any difference between them and mid-range lenses except maybe wide open or at extreme enlargement. The build quality was much better for the premium lenses, but the size of a 35mm negative seemed to set the image quality limit, not the lens.
