I converted this lens to Minolta/Sony mount via a focus confirm m42 adapter. Had to remove a little metal from the inside to accomodate some projections from the Leica lens.
The lens is manual focus and a two lens doublet design. It focuses via a sliding tube at the front of the lens. It breaks down into two halves which makes it reasonably easy to carry.
These were taken using a monopod in combination with a shoulder stock that comes with the lens. I'm still getting used to it and today took 109 shots of which 9 were acceptable.
