Hello,

Indeed, that's the logic. Now the other way around, I was wondering about digital SLR. I never saw one on the inside, but since the detector is smaller than the 35mm film area, the mirror also will be smaller. Nevertheless, they use the same lenses as 35mm film SLR's... what's all the superfluous flange distance used for? Just empty space?

Groeten,

Paul,

But consider this. Pentax 645 cameras are SLR type... So the mirror,
being rather big in size still has to make its move...

It seems to be rather obvious that flange distance of 645 cameras is
bigger than that of 35 mm cameras. However, perhaps there is a an
adaptor (with glass) that takes care of that. Though I doubt such
thing would be made - very little reason to make it.
