Thanks Graydon and Tim. I don't own any SDM lenses, screw drive only! I don't want to install this update if it's not useful for the old drive also. Wasn't one of the updates for the K10d or K20d to enable SDM lenses? I sure don't want to install if it disables screw drive autofocus. Regards, Bob S.
