This filter is great, very good quality. I like being able to mount it on multiple lenses with its included adapters. The pouch is convenient for storing the filter during transport.

Since it is an EOS mount, different lenses can be used based on it.

The lens adapter is very well made and has hardly any play as other adapters are reported to have. The tripod mount is fixed to the adapter, not interchangeable like the original, but this also brings better stability, so from my point of view, better than the original. Focusing and aperture control works perfectly.

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!

bought three adapters with a Canon R mount (one for Leica R, one for Contax and one for Minolta MD). They all reach exactly infinity. The internal anti-reflective paint is well finished. When I check them with a caliber, the two sides of the adapters appear planar (but I don't have any wide-aperture lenses to test that on). On the camera side, they are all precise and without light leakage. On the optical side, I noticed a slight light infiltration on two adapters. Of course, I purposely searched for them by bringing a 500 lux LED flashlight half a centimeter away from the adapter. Light penetration is very unlikely in normal situations (perhaps on an easel on the beach in August). I solved it anyway with a small rubber grommet. If you're shooting freehand, that's not necessary, the hand is hiding a possible infiltration. Overall they look like good adapters to me. Due to their robustness, they can withstand lenses up to 600/700 grams. However, I would not mount lenses that are larger than one kg on the nose.

I usually buy K&F Concept adapters, but since the design is clean, this time I bought a K&F Concept adapter. It's not a problem, but the mount on the lens side was a bit stiff and took some force to remove. So I bought a K&F Concept product for the E-mount but not much has changed.

I have some adapters from Fotodiox, but this adapter is in no way inferior in quality. If the K&F adapters are in stock, I'm happy to use them. OM and M 4/3 Mount fit perfectly!

Everywhere I look: Adapters I see 'Metabones' Bandies through. This one is a third the price, all steel, has an aperture ring [albeit a tight unmarked limited split] - it snaps into place on my 150mm macro Nikon G-Type with a secure, and is just as smooth attached to the camera mount. No effect on IQ, you get no aperture in your exif data. So just keep notes if that's important to you, and it's pretty sturdy, no major wobbles. Can't fault it for the price and may buy a few more brands for other mount types.
