As a follow-up to my overwhelmingly popular October 2013 infinity test with a preproduction Sony a7 and various rangefinder lenses, here’s the infinity shootout I really wanted to do back then… between a regular production Sony a7R and Leica M9, with a similar, though not identical, collection of a couple dozen mostly rangefinder lenses… Unfortunately, this time I’m not one of the first in the world with the results! Please refer to the a7 shootout for an explanation why infinity focus is such a ‘torture test’ for these lenses and cameras.

Sony RX1 Sonnar 35mm vs. Leica M9 and Biogon 35mm ZM lenses review

Sony DSC-RX1 Carl Zeiss 35mm f/2 Sonnar vs. Carl Zeiss 35mm f/2 Biogon ZM comparison review

The Sony DSC-RX1 ultra-premium compact full frame camera with Carl Zeiss 35mm f/2 Sonnar lens has received a lot of praise for its technical achievements. Not only is it the smallest camera in its class (it’s perhaps in a class of its own at the moment), but it also attains very high levels of image quality, comparable to what one can produce from full frame interchangeable lens systems.

The Sonnar lens is the purpose of this review. More specifically, an examination of how well it and the RX1 hold up against currently available Carl Zeiss 35mm ZM-series lenses on the Leica M9 full frame 18MP camera.

Why the ZM lenses and not the ZE/ZF lenses? For a couple reasons:

1) It has been stated by some that for the price of the RX1 and a few accessories, one comes into used M9 territory. This is more so the case now that Leica has released the ‘M’ and used M9 prices have dropped below $4,000. For ‘only’ another $1,000 or so, one can add a quality ZM lens to the M9 and benefit from an interchangeable lens system not much larger in size with more flexibility than the RX1. Both options are much smaller than currently available full frame DSLRs with Zeiss ZE/ZF lenses.

2) I happen to use the M9 and am curious about how well the RX1 compares, and have access to both ZM 35mm lenses. If time and opportunities permit, I may revisit this comparison with some additional Leica M-series lenses.
