It is indeed a terrific combination. For a few years, I was doing extensive travel and took the Mamiya 7 to Asia/India every month. Here is a shot using the 50mm taken in Chennai:
This image, taken on Tri-x after an overnight flight from Singapore, shows the square rendering of the hotel front while taking in everything else. The print just sings - my scan does not do it justice. My website is far behind my photography so look accordingly..(I have a long-standing to-do to update this summer).
I still have a freezer of Verichrome Pan 120 that I process in pyrocat just for this camera - the images are liquid while being sharp.
Sorry for rambling...I love this system..
