Leica's new full-frame, M-series wide-angle is a 37mm equivalent when mounted on the M8 digital rangefinder.

This $1,495 28mm's most unusual feature is the new "6-bit code" engraved into the bayonet flange. It joins the much-admired Leica 28mm f/2 Summicron, which we called "unsurpassed" in our July 2002 test report. Read the full test here
