Pretty good, Rich! I must admit I'm using much more the Contax G-Sony E mount adapter from Techart, because I really like those lenses, but when I'm using the M mount ones, it's very nice. I must say, though, that I've been so busy that I haven't had time to properly set it up, so I know it can be much more useful than it is at the moment. But it is really well engineered and it works very well. Thanks for your collaboration in getting it!
