There is a reference in the R7 brochure, page 22, to a Leica Test Results Brochure #942 220. It is preceded by the comment "This meticulous craftsmanship is confirmed by top results in publications around the world". I have checked with Leica USA and Leica Solms with no success to find this brochure. Has anyone seen it (not the R7 brochure, but the test brochure), and can you summarize what was said (which publications, lenses, and tests?).
