Quick Summary
The K&F Concept Nik to EOS lens mount adapter is a manual adapter for using Nikon Nikkor F/AI mount lenses on Canon EOS EF and EF-S mount camera bodies. It has no electrical contacts, so control is manual rather than electronic.
This adapter is aimed at buyers who already know their lens mount and camera mount match the stated combination. If that is the setup you need, the key points are the lens mount, camera mount and the fact that focus and exposure are handled manually.

What to Compare Before Buying
- Lens mount: Check that your lens is Nikon Nikkor F/AI mount, not a different Nikon mount.
- Camera mount: Confirm that your camera body uses Canon EOS EF or EF-S mounting.
- Manual operation: This adapter has no electrical contacts, so it suits manual control rather than electronic lens communication.
- Use case: If focus and exposure need to be handled by hand, compare this with any adapter that offers electronic functions.
Compatibility, Size and Fit
The stated compatibility is for Canon EOS EF and EF-S mount SLR cameras, with examples including 1D, 1Ds, 5D, 7D and several Rebel models named in the product text. The lens side is for Nikon Nikkor F/AI mount lenses.
Because adapter fit depends on the exact lens and body mount, check both mounts carefully before choosing an offer. Mount type is the main deciding factor here.
Before You Decide
Confirm that your lens is Nikon Nikkor F/AI mount and your camera body is Canon EOS EF or EF-S. Check whether you are happy with a manual adapter that has no electrical contacts. The all-metal construction is part of the adapter’s build, but the main purchase check is still correct mount match.
A Simple Mount Check
Before fitting the adapter, line up the lens mount and camera mount details with the markings in the equipment documentation. A quick mount check first helps avoid choosing the wrong version and keeps the decision focused on the exact lens-camera combination you want to use.
