The Leica Summicron-M 35mm f/2 ASPH. ($3,195) is a wide-angle lens for Leica and other M-mount rangefinder cameras. It covers a classic field of view when paired with a full-frame body, and is quite compact, especially when you consider its f/2 aperture. It lives up to a stellar reputation and is the go-to lens for many a Leica shooter, but it doesn't quite match the pure optical perfection of the APO-Summicron-M 50mm f/2 ASPH. ($8,795.00 at Amazon) . Still, it's a top-notch lens that won't disappoint, if you can work it into your budget. The Zeiss C Biogon T* 2,8/35 ZM ($903.00 at Amazon) is still our Editors' Choice 35mm rangefinder lens as it represents a stellar value and captures images that are very sharp, but its maximum aperture isn't as great as the Summicron. The 35mm Summicron ( at Amazon) measures just 1.4 by 2 inches (HD), and includes a compact hood and rubber lens cap. Weight varies based on whether you buy the lens in black or chrome. The black version is 9 ounce...
