I've got one of Steve's 110B conversions with the factory 127mm still in place, and have enjoyed it immensely. Nice conversion.

I just recently had him mount a 90mm Angulon on a second 110B body for me, but I haven't had much time to play with it yet. First impressions after one shoot is that it's just as good as the original one, but wide.

I'm a happy camper.
