Yeah, but due to the mirror it's close. Or at least the distance can't be much less (if the distance were greater it wouldn't matter). I calculated for several different film-plane-to-lens-flange distances and the angle doesn't vary much until you get far out of the range of any existing SLR lens mount. And actually, it wasn't fair to call my exercise a "counting of teeth" in the sense of the original story. That'll come when there are actual examples of Contax N1 cameras being tested. -- Mark Roberts www.robertstech.com - This message is from the Pentax-Discuss Mail List.
