I have been unhappy with the contrast and resolution of my Canon 400mm f5.6 and am looking for some alternatives.

Whenever I use this lens, I support the camera on the R55 ballhead and the lens on a bracket attached to the leg of my Gitzo, so I always have two points of support. The MTF curves for the Canon 400mm f4 DO are not any better than the f5.6.

I am considering the Leica R 4/400mm Apo-Telyt-R, but again, the MTF scores don't look any better than the Canon that I have. I do landscape photography and use my 400mm to produce 5-6 stitch photos that are printed 5 feet or more in length.

Has anyone tested lenses in this category, or know of any comparisons done by others?
