Camera Mounting Plate CP2 doesn't quite fit my NEX5.
I can get it close to the LCD but there's about a 0.05 (estimate) gap. I think I can shim it with some electricians tape. Also, the hex screw that holds the lipped plate in place is English -- not Metric. I don't know if that's a concern. It boggled me for a few minutes.
Also, the lipped plate is longer than it needs to be and because I have to move it so far forward, it impacts part of my Samyang Lens -- lifting it slightly and causing a slight misalignment.
If you would only make a lens ring adapter for the NN3/4/5 you would save a lot of people a lot of grief. Mounting a camera on an NN3/4/5 is still the weak link in your product line.
