I just received a Olympus 85mm f2. There appears to be a little bit of 'play' in the focus ring. It's not really loose, there is just less resistance for a short period when I turn it back and forth.
Hmm let me see if I can explain this.
Starting with the lens focussed at infinity, I turn the the focusing ring about half a turn and stop. Then I turn the ring the other direction. There is less resistance for about 1/2inch or 1 cm, then the normal resistance kicks in until it hits infinity again.
Is this normal? Should I return the lens?
