I have to agree with you at this point about the J12 versus the C-S 28. I haven't given up on it yet. I taken only three rolls of film and have been pleased with several. I will say it is sharp, almost to a fault. I think I'll try slower film and see if that helps. I will say that I love my J-12 and regret that it won't mount on the Bessa R, although it looks cool on the Leica IIIc!
