Originally posted by Mikesul This seems likely since the factors causing shutter shock are unlikely to involve the parts replaced in the upgrade. If the SS went away after the upgrade it might just be that reassembly tightened or loosened something which eliminated the problem.
My K1 mark II is not a K1 upgrade. I have two bodies, one K1 and one K1 II, both purchased new from Ricoh, I have compared the same images taken with both bodies and the same DFA28-105 lens, K1 images are blurred, K1 II images aren't blurred. So there is something with the shutter block of my K1 that's not the same as the shutter block on my K1 II. My K1 makes a more distinct shutter noise than my K1 II, the K1 II sound is softer.
