Review on Concept Adapter Mount Camera NEX VG10 by Jennifer Williams

Bought 2 of these to attach the Pentax K to the Sony E mount for my Sony A7. They worked so well I ordered 2 more Nikon Sony adapters. Unfortunately, one of the adapters on the camera with my Nikon 50mm AIS lens was so loose that I couldn't use it. A strange tripod base was mounted on another mount. The problem is that it sticks out and isn't needed for a 50mm lens. Unfortunately, I can't just unscrew it because it's attached with screws and the holes go all the way to the inside of the adapter. Therefore, if I don't plug these holes in some way, light leaks out. This option doesn't suit me, so I'm returning both. I'm giving 2 stars instead of 1 because the Pentax adapters actually worked.
