Shootout: Leica 90mm f/2.4 Summarit-M vs Leica 90mm f/2 APO-Summicron-R ASPH (Green Lichen Barn Exterior)

Get Leica 90mm f/2.4 Summarit-M and Leica 90mm f/2.0 APO-Summicron-M aspherical at B&H

In Guide to Leica, this comparison answers a practical question: in what ways is it worth spending for the slightly faster APO 90mm?

Shootout: 90/2.4 Summarit vs 90/2 APO-Summicron: Green Lichen Barn Exterior (M240)

The question is answered unequivocally.

The Leica 90mm f/2 APO-Summicron-R ASPH was used, which is optically identical to the Leica 90mm f/2 APO-Summicron-M ASPH. The R version has the advantage of being directly usable on Leica M or Canon with a lens adapter, or convertible to Nikon mount, and I prefer its ergonomics over the M version.
