Ben, one of the reasons you fit so well with this crowd and this particular game we're playing with manual focus lenses is your willingness to push back when challenged by the wonderful humor that we've developed here. As Laura observes you were willing to play Devil when it came to dangling lenses in front of people while at the same denying that had happened at all. But really everyone is playing that game on some level... challenging decisions other have made and pointing them to other possibilities... hence the kit building motto.
I would say, at least for me, kit building will never involve ANY camera that requires an adaptor to mount these lenses in the same way that I'd never consider buying a pre-AI len and cutting the aperture ring. Yes, the Df takes very good care of me with regard to both of these matters. I know it isn't the best camera on the market at the moment, but it works.
Glad you drop by from time to time. Now you can shame your friend Philippe into joining us... wouldn't that be fun?
