SMC Pentax-L 43mm f1.9 Special motor drive 5x MC filter for 49mmYes, Pentax did make Leica thread mount lenses! That is to say, they made one specific model (this one) and only 2000 in total. But it's a great lens, with a useful normal wide focal length, a fast f1. 9 aperture, and excellent imaging. It's a Leica thread mount lens, but it's compatible with any M mount camera using the included adapter. This example has light paint and finish wear, clean glass, good function.
