I didn't know the K&F Concept brand, but I recently read a positive review about their adapters. I already use adapters from Quenox and K&F (also good quality) and wanted to try this brand. -Coupling with lens: tight but good -Coupling with body: perfect -Infinite focus: good -Light tightness: not measured -Material and workmanship: good -Operating aperture with G lens: good -Coupling with pre-AI lens: good -Price/quality: good In short, great product!

Purchased to use Sigma 50mm macro, Nikon mount, on my XT3. After some uncertainty with pairing the adapter to the lens (instead it fits perfectly to the camera body) I have to say I am fully satisfied. The optics maintain good quality in both photos and videos. It also looks well built so I hope it lasts a long time.

The product arrived as described. To work with xt4 you need to select a shot without a lens

Great product. Well made and top quality I must say! I already have 3 and each one is just like the other. I can recommend it with a clear conscience.

Highest manufacturing quality Used to mount Canon FD lenses to a Fuji XT4. I highly recommend this product. Good manufacturing materials and no modifications.

The ring was used to attach a Tamron 70-200 F/2.8 in A-mount to my A7s in an E-mount. Quite difficult to attach it to the A7 on the lens side and the soft side (it's better than the other way around...) The diaphragm ring is easy to handle. Infinity is maintained. The price is still quite expensive but the manufacturing quality is evident and the results are there: no play on either side of the ring.

K&F is the best lens adapter manufacturer in terms of value for money. Compared to the original version, these are much lighter and have an attractive outer coating. The inside is well flocked and doesn't have a shine like other cheap Fotga or Fotasy adapters. Compared to the third generation, the build is about the same, but the newer ones work much better and look better. I never understood the flat, square look of the generation 3. I would choose these adapters over any other brand.
