Fast delivery. Good and nice packaging. There are many different connection adapters for all common lens sizes. The drawers were a bit too tight when delivered, but I loosened the screws a little and then it was ok. I didn't notice any color casts in the filters, which I think is good

Admittedly, the system of magnetic filters is not entirely new and I cannot say who copied from whom, but I already know K&F from their very good lens adapters and solid tripods. And since I've been flirting with magnetic round filters for a long time, but up to now the prices for such a system have seemed too steep to me, I was of course interested that K&F now also offers something like this.

I have an old Canon 550D and some Lens. And now I've bought a Canon eos m100. I want to keep using my EF Lens. Then I buy adapters. This works perfectly and can autofocus very quickly.

Mounting Nikon lenses on the XT2 and this adapter works very well. No sacrificing quality as there is no glass, it is just a mock adapter. I've tried various Nikon G lenses and Zeiss ZF mount lenses and had no problems. The mount or lens doesn't play and it feels secure. As with most other adapters, there are no aperture markings at all, leaving you guessing with any lens that doesn't have manual aperture controls. At this price you really can't go wrong!

There is no shortage of excellent reviews for Fuji X lenses, but excellence comes at a price. Fuji glass, especially the Primes, is far from affordable for most enthusiasts. For Nikon photographers who want to take advantage of the iconic performance and great JPGs of the Fuji X bodies without a camera, but don't want to spend a fortune on Fuji's primes, this adapter is a real option to get more life out of 'Old Faithful', the Set of outstanding Nikon F and G lenses that many Nikon shooters have in their inventory. The side between the lens and the adapter seemed a little tight for the first few mounts, but has become very smooth with a little use. Lenses can be mounted without play. The built-in aperture ring allows for proper opening and closing of the aperture on G lenses. As many have pointed out, the aperture modulation travel of Nikon glass is very limited, so you may end up driving the lens further down than intended. Of course, there is also no way to know the exact aperture when using Nikon G lenses with this adapter. Once users get used to manually focusing with their Nikon glass when using this (and other) adapters, and this shouldn't be difficult given the focus peaks of most Fuji X APS-C bodies, they might come to the conclusion come that the combination of Nikon lenses and Fuji X bodies is something special. Who would have thought that the drawer full of Nikon lenses on Olympus, Sony and now Fuji bodies would be revived over and over again with adapters.

Thank you very much.

Adapter is solid and well made. I love the button on the back for removing the ring off a lens. It's much easier to use than the metal tab some other adapters have. The only small inconvenience is not being able to switch lenses on the camera without having to remove the adapter as well, but the button allows for switching lenses relatively quickly without much fiddling.
