I purchased one off ebay, with tripod mount. It appears to be well-made, with 4 screws instead of 3 attaching the Nikon mount plate to the body. I've picked up some MF lenses to try on my a6000. Some are recommended legacy lenses, like the Vivitar (Komine) 28mm f/2.8 Close Focusing wide angle, the Series-1 28-90mm f/2.8-3.5. But I find their results to be unsatisfying. The wide angle is soft at the edges no matter what f/stop, neither could focus to infinity. Before I deem this lenses to be duds, I suspect the adapter could be at fault. I read this is a common issue with cheap adapters. Sanding down the body was a solution found online. But this adapter has a raised lip to seat the plate. So it can't be sanded down without great effort. I'm looking for an adapter that you folks have experience with your Nikon mounts that works well and can recommend. So far, none of my adapters have been 100% satisfactory. A Fotga Minolta MC/MD adapter has play at the Sony body interface. An unknown Olympus OM adapter with tripod mount is machined with misaligned holes, therefore the tripod mount is to one side, and lens isn't aligned to the body, nor the tripod mount. I realize it's hit or miss on ebay. What do you folks use?
