Leica M39 Mount Lens to Nikon Z6 Z7 Camera K&F Concept Lens Mount Adapter

Works perfectly with my Z5 and Minolta lens collection. Lenses install and remove easily. Images look great and focus fine (sample image posted).

K&F Concept lens adapters are well built and accurate with excellent infinity focus characteristics. All metal construction with high-grade finishes makes this an excellent choice for adapting legacy manual focus glass.

Fits my old Canon FD lenses perfectly and secures to the Nikon Z-mount without issue. It works exactly as described. Using my ancient, but still beautiful Canon lenses on the new Nikon is an unexpected joy!

Bought this when I upgraded my camera so I didn't have to get rid of some of my favorite lenses. It works exactly how it should and fit both the lens and camera.

I got the Canon EF Mount Lens to Nikon Z6 Z7.

Could be smoother but it does the job

Seems fine and mounts my Minolta MC lenses to my Nikon Z30 without issues (manual focus and aperture only, as expected).

I use this to adapt the Zeiss and Yashica lenses from my old Contax RTS film camera to my new Nikon Z7ii mirrorless electronic camera. The mount doesn't seem to go on quite as smoothly as the OEM lenses do with the original camera, but once they're on, they seem secure. Of course, the old lenses have to be manually focused, but seeing as the camera has a built-in app for manual focusing, that's not an issue. The old lenses produce some EXCELLENT images - they should, as even 40 years ago there were sophisticated mainframe computer design tools for optics, and the Zeiss engineers knew what they were doing and made some really good glass. This adapter lets me keep them in service.

K&F makes quality stuff, or sells quality stuff. I got this for an old school Nikon F3 F mount lens so it could mount to my Nikon Z7. Works great and has a marvelous fit and finish. Note that It's purely an adapter and not like the Nikon FTZ II. K&F doesn't claim it does anything other than that, so they're very upfront about it. But for what it does, it does very well.

Fits my Nikon z6. I can now use some old sigma Minolta lenses I had from a old 35mm camera on my Nikon. Works in manual focus only, (which I knew this when buying). Very nice, seems to be good quality.

I got this adapter to adapt my Nikon AI-S lenses onto my Nikon Z 7 since it is much cheaper than the FTZ adapter and these lenses do not require electronic contacts. One thing that I immediately noticed was that the Nikon Z lens cap did not fit snugly on the adapter, which led me to suspect that there might be some play when attached to the body.

Sure enough, I attached it to the body and there was just the slightest bit of play between the adapter and the camera body (something not present at all with my FTZ adapter). It wasn't enough to get me concerned, but it would have been nice if it snugly with no movement at all.

On the lens side, my Nikon 28mm f/2.8 AI-S fit snugly and there was no movement at all so no complaints on that end.

I did, however, notice one odd issue that popped up on the Z 7 with both this adapter and the FTZ adapter. Neither adapter will display the aperture setting of the lens. That's annoying, but you can work around it. Something that might be a deal breaker, however, involves the camera body itself. As of right now, I cannot get a meter reading on the camera body with either lens. This is not to say that the meter does not work as I've found Aperture Priority Mode to be accurate, but I like to shoot in Manual Mode with the LIVE EFFECT setting off and this is simply not reasonable on the Z 7 right now unless you are going to "Sunny 16" it. So just know that as of this writing (unless there's some setting I'm missing in the menu), you will have to either shoot in an Automatic/Semi-Automatic mode or rely on the Live View exposure in your EVF (or your In-EVF Histogram) as your actual meter reading will disappear in all metering modes. This applies to both this adapter and the FTZ so it's just a camera thing at this point that you'll have to consider.

The 1-Star off is really just for the play between the camera body and the adapter.
