Up for your consideration today, a Canon 50mm f/1.8 Lens for your Leica Screw Mount Camera. Plus: -Generic M39 to M Adapter, for use on M Mount cameras -Canon metal front cap -Generic rear M cap -Infinity lock removed, pretty common modification for better usability That's right, the ame 50/1.8 that people keep talking about. One of the real bargains of the Rangefinder world. I've been using it on my Voigtlander Bessa R2A for the past 2 years, and it's been my favorite. Selling because I've got a 50/1.5 and I tend to use SLRs more today, so it's time to downsize. Obviously couples to my rangefinder accurately, glass is fine, the usual dust you expect in a 50 year old lens - nothing affecting image quality. Aperture is spot on, some very very slight oil on blades. A good specimen of this particular lens that I've simply found a joy to use. Serviced locally last year, but focus can be a little resistant at just one point in the close range. If it bothers you, you can have it lubricated, but it never did me. $180USD, plus shipping from South Australia. I take PayPal. Last attached photo is an example of the results I've gotten with this lens.
