The lens seems to do fairly well, at least stopped down, based on the first roll through the camera. Colour and contrast look decent, especially for the price which was peanuts. I still need to work out my digitisation regime (probably buy a scanner) to be able to share things but I'm enjoying using the camera, and not having to use a computer to see the results - for now at least. Looking down and realising I have a Leica hanging on my shoulder hasn't worn off either.
Got another roll to process now - including pictures of a friend's kid playing with her new birthday toys, which was a test for my fledgling rangefinder focussing skills!
Yeah it takes some time to learn zone focusing and how to focus with a rangefinder but with a little practice and once you get it you will probably never go back to auto focus and yes there is something really enjoyable about shooting with a rangefinder and in my opinion Leica rangefinders are the best.
