I recently purchased a Leica CL with 40mm f2, and I am looking to get a wide-angle for it. So far, the only options I've found that are somewhat affordable are the 28mm Leica/Minolta lens, Canon ltm 28mm with an adapter, and the 28mm biogon for G-mount with an adapter (which I can't find the right adapter for.) So, my questions are: 1) Can someone possibly send a link to a reasonably priced adapter G-mount to M-mount? 2) Does anyone have experience with adapting lenses to M-mount, and how it works with the framelines? 3) Are there any other options that I should be considering?
