Thanks again for the input, I picked up an Olympus 35 shift (just ran across it - it was very reasonable and it had the EOS adapter with it) so I'll test it later this week. I was hoping to get the Pentax 35FA with the Zoerk, but I have not found one yet, but I'll keep my eyes open.
I hear that the Pentax 33-55 FA zoom is also very good, sharp, with a large image circle, have you guys put this though it's paces?
