This is Voigtlander's 25mm f4.0 previous version lens. It has the same optics at the current version, but is not rangefinder coupled. The lens is extremely compact and has a focus tab. It includes the very fine companion 25mm optical viewfinder.
Glass, cosmetics, and functionality are all excellent. No issues at all with the lens.
At CameraQuest, the rangefinder coupled version is $419 and the viewfinder $209.
This lens is very sharp, with good contrast. On a full frame body, it makes a great street lens for those who shoot with external viewfinder and hyperfocally. The lens has click stops for 1m, 1.5m, and 3m. It also makes a great normal lens on m4/3 bodies.
Price: $350 (includes USPS shipping) via Paypal. CONUS sale.
