Author Message   Niko Koskela Rating: N/A Votes: 0 Posted on Tuesday, March 15, 2005 - 11:10 pm:    I have disassembled a SMC-Takumar 1:1.4 50mm for deep cleaning. When putting it together i repeatedly end up with the same problem. The aperture ring turns normally, but turning the aperture ring from f11 to f16 doesn´t have any effect on the aperture. I have not been able to find a way to correct this. "Googling" for this problem only found me a couple of referrals to "aperture calibration", but not any instructions to do it. Could anyone help me ? Cheers, Niko
