↑Leica M9 and Zeiss ZM 21mm @ f/2.8.

The focus was on the boat, of course, and you can see the out-of-focus treeline and fog in the background.  Just how sharp is the Zeiss ZM 21/2.8?

↑ Zeiss ZM 21mm @ f/2.8 (100% crop, no sharpening)

Clearly the Zeiss, beyond being sharp and possessing incredible resolving power – beginning at f/2.8 – renders in a contrasty and substantial way (for lack of a better term)… elements seem to jump out of the image (the so-called 3D effect) despite the large depth of field a wide angle lens normally affords.

A truly remarkable lens.
