35mm · f/1.7
The Voigtlander 35mm f/1.7 Aspherical Ultron is praised for exceptional sharpness wide open, even at f/1.7, with controlled flare and decent bokeh. Weaknesses include heavy vignetting, especially on digital, and a thin focusing ring that some find less pleasant. Build is all-metal and solid, with smooth aperture clicks. It suits those wanting a compact, sharp 35mm for Leica M or adapted mirrorless, but vignetting may require correction.
