Originally posted by Sean Nelson Wow, is it really that slow? Back in the early 70's my Bronica S2A synced at 1/40s, and that was a 6x6 camera so they couldn't get away with a shorter run for the shutter curtain by having it traverse the narrower dimension of the film.
Looks like I had it wrong, according to this page
PHOTOgraphic Magazine Online: Pentax 645nii the 645N II has a 1/60s flash sync.
Still I find it to be a bit to long. I'm not sure what the fastet sync speed on a existing 645 is, but I see the Contax 645 has 1/125s and the top of the line new Hasselblad, the H3DII can sync all the way up to 1/800, but as I understand that is because all the lenses have their on shutter.
My personal belief is that on a medium format the sync speed should at least be 1/500s - and if that is not possible with a shutter in the camera, then all the lenses available should have a leaf shutter inside.
