I have a number of old Konica AR lenses, many from the 1980's. In terms of quality my experience using them on my Panasonic G1 has been very positive. However, that is a crop sensor which selects pixels only from the centre--the best part--of the lens.
I recently got hold of an adapter that would allow me to fit these lenses onto my M9. I wanted to try the 135mm. The lens fits well on the M9 body, and does not block the view finder. But there is a catch. The rangefinder focusing mechanism does not work, leaving only the distance markings on the lens to estimate the focus. Shooting hyper-focal is an option, but with a long lens the range in focus is not that deep.
As I begin this experiment the focusing process is iterative. Fortunately years of computer science have taught me many search strategies; I've started with a binary search method.

In the 1950s Magnum created portfolios for "Generation X". Every photographer was given a group project: the task of portraying the new generation in the country he was visiting. The selected individuals were each interviewed using the same questionnaire, herein creating a fascinating portrait of a future generation. "Generation X" was published throughout the world. This video highlights Werner Bischof's trip to India and Japan and the people he photographed and interviewed on his journey.
I came across this training / review video posted on YouTube. Must see for anyone who owns or is considering a Leica Camera.
