I have used a Mamiya 7 for years and have not noticed any light fall off in the corners. The M7 has no weaknesses other than price.

Some Yashica Ds have the Yashinon 4 element Tessar-type lens that is a good performer. Some have the mediocre 3 element Yashikor. The cameras are surprisingly light and actually handle better than the crank wind TLRs. I learned photography on one in 1964.
