I used this filter on my Canon Rebel T7 with EF-S 18-55mm IS II lens and a size larger adapter. It works beautifully, crystal clear, screws on with ease. It comes in its own hard case with a cleaning cloth.

These were a huge help for my photos. Great quality and lightweight. I use with my canon rebel t7 and have no problems.

This adapter opens the lens of my Leica camera with a Canon lens

Since I recently inherited a Nikon FG-20 as well as a Nikon Micro-Nikkor 55mm f/2.8 and a Nikon Series E manual focus zoom 70-210mmf/4.0s, I naturally wanted to use the old lenses on my Canon EOS 600D or EOS 600D Review Canon EOS 760D. But: Nikon on Canon? It is well known that this is not possible without an adapter ring. Novoflex adapters were out of the question for me, because as a hobby photographer and occasional "analogue photographer", I didn't want to spend €100 on such a ring. Nevertheless, I wanted to break THE primal law of photography and combine Nikon and Canon. K&F Concept offered a cheap alternative for just under €20. The adapter ring is surprisingly high-quality and made of metal, and it can also be quickly mounted on the lens and DSLR. I was surprised by the results (see photos) and would not have thought that the two 30-year-olds "harmonize" so wonderfully with my EOS, to put it bluntly. It's a bit "hooky" to detach the adapter ring from the lens again using a tiny little "hook" (if you can call it that...), so the ring gets a star deduction, because it gave me a bit of a panic at first and I'm not sure how long this "hook" will go along with the whole procedure. ! A NOTICE ! You should really inform yourself in detail about the bayonet (connection of the lens) beforehand. Since the two Nikon lenses are both a bit older and were built in a time when people would have laughed about something like the internet in this country, it was a bit difficult to find out exactly (especially as a layman or newcomer to Nikon and analogue photography) whether they both have the same connection and whether I might even have to buy two different rings.

I added this to my Canon Rebel T3i camera. The camera is a few years old and I love it. Cleaning the lens is always a chore, you need to get out the right cloth and be careful not to scratch it! But I can just use my shirt with it. If I scratch it it was $20 and I can get a replacement. I'm really happy with it!

The product meets my needs to serve as an adapter from a Nikon lens to my Canon camera. The only problem has been that I had to do a lot of research to make sure the lens worked. In the product description they are not too specific. Otherwise perfect and received within 12 hours of ordering

I still had two prime lenses from my film camera, a 28mm and a 50mm with filters. The adapter works fine, I've attached a photo (the one with the flowers) I took with it and the 28mm lens. It focuses to infinity and the sharpness is ok (UV filter was on). Focus and aperture must of course be set manually. But you have to make sure to set the adapter to "Close", otherwise the lens remains open, you cannot adjust the aperture and light comes through. I use this sometimes to create a "soft glow" effect like in the photo with the sofa.

With regard to the adapters from various manufacturers, which were often not exactly positive and the mostly positive voices about this product, I was very curious how the adapter would interact with my old lenses and the EOS 600 D from Canon.
I tested the adapter with old original Canon lenses:

1. Macro lens 35mm - Various plant motifs were photographed and the result was impressive. The objects to be photographed were also displayed on the camera's fold-out screen. In some cases, however, I had the impression that the light sensitivity setting was not reproduced faithfully on the screen. But after I experimented a bit with it, it worked satisfactorily.
2. Zoom lens 70 - 210 mm - The zoom lens can be focused without any problems even with the largest zoom factor (which has been criticized with many other adapters. The images in the viewfinder are displayed correctly on the camera screen. And the resulting images are flawless.

The The adapter itself can be easily attached to the camera and does not come loose when changing the lens. The two lenses used could also be attached to the adapter without any problems and are firmly in place.

Overall I am totally satisfied with the adapter. I do not know if a professional would do the same would see, but for me the resulting images are really good, especially when you consider how much money you save by using the old lenses.
