Canon 50mm f1.8 for LTM format_Something Else Now: it's worth noting thatThis is a classic Canon 50mm f1. 8 rangefinder lens for the Leica Thread Mount. In excellent cosmetic condition, with minor finish wear. Smooth focusing, good RF coupling. Glass has a few small areas of light haze near one edge which will not affect imaging, as well as very light cleaning marks. Classic rendering, nice and sharp stopped down a tad. Includes rear cap.
