Things I need to do for my NIKOR 50mm 1.2 to mount on 5D MK3
I use this to adapt my Nikon 50mm 1.2 lens to my Canon 5D MK3 DSLR.

Disclaimer: do all this at your own risk as you will probably void your ability to return the product or your warranty. Perhaps try deferent Adapter brand which I don't have the option at the time.

NOTE1: Don't get tempted to start shaving metal out of your NIKON Lens mount, It may look like one of the mount bayonet is bent (and causing it not to fit) but you should not need to modify your LENS, specially when it mount just fine on a regular NIKON camera.

NOTE2: Also don't cut the the extended long PIN from the NIKON mount (find 50mm 1.2 lens pic online to see what I mean), only do that as a last resort. the Camera may not release the shutter properly due to #2 below. Although It's possible that long pin interfere with the contacts but make sure that is the case or you modify the lens for no reason.

First time I tried to mount it, it did not mount well, after some tinkering I need to do the following to make this K&F Adapter work:

1. Shave of the outer diameter of the metal plate ring (on the NIKON Side of the adapter - you need to remove 6 screws and use either sand paper or a file to shave the outer diameter) so that the lens can properly mount to the adapter. When you have enough clearance your lenses should mount/dismount easily and the aperture should slide smoothly (similar to when the lens is not mounted).

2. on 5D MK III there is a micro switch in the camera that should not be triggered if you are using manual lens (Looking at the camera lens opening it is on the left side under the prism). it will be pressed by one of the Adapter bayonet mount, so you need to shave the mount foot a bit so it won't press the switch (or don't mount the adapter all the way if you are fine with the adapter not locking completely).

That is it, good luck!
