I read somewere (here?) that you could adjust infinty on Zuikos but removing the rubber grip and loosen the screws beneath. I just won an auction on the 21/3.5 (yay!) and when it arrives I want to make sure that it focusses correcty. Looking at a copy of the 35 2.8 I find four screws that are shallow and one that is deeper recessed into the barrel.
Should all five screws be loosend?

I had to make some adjustments with a couple of my Zuikos, but its not difficult. Simply remove the rubber focus grip and loosen the grub screws underneath (there are three screws, and appear to be spaced equidistant from one another).
A word of advice to add: take a marker and mark where the front and rear helicoids align. It is possible after loosening the grub screws to separate the front and rear helicoids. If you haven't marked the alignment, you'll have a nearly impossible chore reassembling them.
I had to send my 55 f1.2 off to John Hermanson to get it reassembled after very stuidly taking it apart. He did a great job on the repair, but it added significantly to the cost of the lens.

Yep...that happened to me with my Zeiss 85/2.8...ended up sending the lens to Mark Hama for repairs. I didn't realize just how short the screws were on the Zeiss as compared to those on my Zuikos...adjusting the Oly's was a piece of cake. Lesson learned...
