Not true. ah - here's the crux of misunderstanding :^) The assumption was that a 400mm for 645 would function *the same* - ie: the sensor would crop into the lens' image circle and the *resulting image" would seem (to an eye not overly concerned w/ the physics of DOF, etc) as if the lens were longer than it actually is, mostly just a reduced field of view effect. But that's what the people seem to really like - you know, a Free Lunch! ;^) Bill --------------------------------------------------------- Bill D.
