My father-in-law gave me a Nikkor in f1.2 50mm! To adapt it to my Canon 70D I had to take a ring ... it is really nickel I do not regret my purchase! No play and does not catch it can be put on and taken off without any problem! I recommend this object to buy with your eyes closed.

After finding two lenses from an old Yashica of my father at home, I pushed myself to buy this product because I was curious to try them on my digital camera.

Packaging:
The product arrives in a normal Amazon package and inside the small box you see in the photo. There is also a small sheet with all the company contacts written on it.

Product:
The adapter looks good, is solid and seems well made. Installation is very simple. I only had one small problem: once connected to the 50mm f1.9 of the Yashica, I was able to unscrew it later, to be able to try it with the second lens, a 50mm wide angle. Mounted on the latter, I was no longer able to disconnect it (which forced me to buy another adapter). No big deal, in the end it is much more convenient to have an adapter for each lens, perhaps however by turning to other cheaper and equally valid products. Overall I was happy with it, the adapter perfectly anchors the lens to my camera (Canon 1000D) and I never noticed any strange movements or noises. The camera will not detect the aperture of the frame and you will have to focus manually.

Finally, I was happy with this product, good price and excellent quality. I recommend it to those looking for something that works without spending a fortune: in the end €20 for a practically new lens, is more than good!

It works very well.

Listing was a little flawed. I thought that this adapter could be used on the F, AI, and AI-S as well as the G lenses. After trying it, works well on the G lenses (lenses without the aperture numbers on the lens mount) I still give it 5 stars because it's works well and provides the ability to adjust the F/stops in AV and M settings.

Fits perfectly

I got a great deal on a Canon 5Ds and found I could use my Nikon lenses with this adapter. Perfect. In 30 years I've invested thousands of dollars on Nikkor lenses but always wanted to try out the Canon, and now I can. Sure you have to manually focus and stop down the aperture, but I was doing that for half my life with manual cameras so no big deal. Just the cost savings alone using my existing 300mm/f2.8 lets me buy another camera - wow. Highly recommended!

Used this for my canon 60d i needed to attach a Nikon Nikkor 50mm. Fits perfectly

This adapter needs (Nikon lens to Canon camera) needs to operate in 2 or 3 mm between seating surfaces to maintain proper focus. The biggest technical challenge is to fit a mechanism (a tiny lever) that permits alignment pin release from the adapter to the lens. I had a cheaper adapter in which the pin mechanism failed and the adapter had to be cut off. This K&F appears to be better built.
With any adapter like this, I would suggest you carefully examine the pin mechanism before you attach each time. Be sure the parts are not bent and the tiny screws are not loose.

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!

Just what I needed! Using it on a Sigma Nikon F lens to a Canon T2i body, manual aperture and manual focus (that is, NO autofocus, NO aperture control from the camera body), everything else working on the body camera.
