Subject: [Leica] OT: large format lens vs. medium format lens

Always been my understanding of it, not the same enlargement so not the same 
lens resolving. Newer LF lenses are much better than most old ones though....

As Iwas formulating the question, it sounds like the answer IS obvious, but 
just want to confirm.

I am testing the Shenhao 617 and it could be my focusing techniques and 
other issues, but it appears to me that the images are not as sharp on the 
same film as images made by, well, the Hassy SWC.

Yes, I am expecting someone to jump in and say of course the SWC is razor 
sharp because it's the legendary Biogon etc., but I am now thinking that 
this generally will be the case, as the large format lens are designed to 
cover large negative (and the smallest 4x5 dwarfs the 617) so they do not 
generally have the resolution and sharpness that a good medium format lens 

Is this correct?
