planet5D: New Nikon F-mount Option for Canon EF Mount Cameras


X-Circle by LockCircle – New Nikon F-mount option for Canon EF mount cameras | planet5D – HDSLR community.

If I’m reading it right, this device does 3 things:

1) Let’s you use Nikon lenses on Canon cameras

2) Has a Positive Lock-like mechanism to secure your lens to the camera better

3) Rotates your lens 90 degrees, so the focus marks on DSLR lenses are shown on the side, where focus pullers can see them.
