Dave quick question. Why would someone use MF (medium format) lens on a 35mm?
Just reading a landscape photograher who swares buy them but didnt say why.
Can they be stopped down a lot more before defraction (think thats the word) kicks in
The only reason I can see someone doing this (beside already owning the lenses and wanting to use what you own) is there are shift adapters for some MF lenses (Hasselblad had them) so you could use the lenses to shift (and I think they had some tilt). The MF lens would cover a 35 mm format.
Defraction is more related to your format so that would not matter. Many times larger format lenses had less resolving power compared to smaller format lenses but that was not a problem as the negs were enlarged less usually (which is also why you can stop down more on a large format lens before diffraction becomes an issue). That would work against them but lens design has gotten better.
