I got this for several of the 52mm lenses I have. It threads on smoothly with no wobble and is made of nice, thick plastic.

One of these lenses is a 18-55mm zoom used on a Nikon DSLR with an APS-C format sensor. The manufacturer’s description says not to use this hood on any lens with a wider field of view than 25mm to avoid vignetting (darkening of the edges of the photo). The crop factor for Nikon APS-C sensors is 1.5x, so at 18mm this lens has a field of view comparable to 27mm on a full frame digital camera or a standard 35mm film camera which is usually used as the reference when describing the field of view of lenses attached to cameras which evolved from 35mm film cameras. Look it up to get a better idea of what I’m talking about if you don’t already know. I’m not that keen on it myself.

Anyway, 27mm is uncomfortably close to 25mm so I ran some test shots of an evenly lit yellowish blank wall with the Nikon to check for any vignetting. The camera viewfinder is not 100% accurate so I had to go with the actual pictures. I found no noticeable vignetting at 18mm as long as the hood was oriented with the two largest “petals” pretty close to 12 and 6 o’clock. I found that to achieve the no-vignette at this position, the hood needed to be screwed in all the way – meaning that the lock ring had to be all the way snugged up to the body of the hood. A partial rotation of the ring to secure the hood with the petals at the correct position was okay, but even a few full “backwards” rotations of the lock ring which prevented the hood being screwed down as far as possible started giving me some vignetting.

Even locked down to the right position to start off there’s a slight rotation of the front of the lens to achieve proper focusing (unless you have one of those expensive lenses that have internal focusing), but the movement is fairly minor and didn’t give me any trouble. You probably will have trouble, though, if you screw the hood onto a filter and then try to shoot at 18mm! If using a zoom lens you could cancel any vignette by just selecting a slightly longer focal length at which to shoot.

Apologies for going on, but the take-away is that you shouldn’t have vignette issues using this hood at 18mm on a APS-C format camera. Canon has a 1.6x crop factor which puts you even farther from the 25mm danger zone. If you have a full frame format digital or a 35mm film camera, you would have major issues at 18mm. So, then don’t use any focal length under the 25mm mentioned. Of course, if you are using a zoom lens, you can use it fine at focal lengths greater than 25mm.

I don’t need to penalize this hood by taking away stars as it seems to be well made and does its job very inexpensively.

These filters are great for a mirrorless lens for my Sony. Quality construction and it's nice to have both UV and CPL in one set. It would be nice to have a case for them, but they're a solid value that does the job well.

Construction, at least apparently robust and aesthetically on top of Sony mirrorless by the orange anodized ring. Perhaps there are more sophisticated products out there than construction, but it does what it needs to do and does it well. For what it costs I wouldn't look for anything else.

am the owner of a mirrorless Sony A7rii and for me the best thing is to revive old glories like the Zeiss 50mm f1.4 which, despite its age, always produces great photos, even on a digital level. This adapter from the K&F Concept Pro series is then really well finished, all metal, adapts perfectly to the camera body and lens, the interior is then matt black, essential for light spots and the result of a damaged photo. We recommend

Yes, it fits perfectly on my Samsung Nx 3000 mirrorless camera and Canon lenses have no problem even if there are no more automatisms.

The adapter allows AF or MF Minolta/Sony A lenses to be used on Sony FE mirrorless cameras. Very well made. The lens can only be used with manual focus, but is fine in most cases. There's an aperture control, not marked with f-numbers but with click stops so we can count off stops if needed. Does the job and allows me to do some vintage reviews of Minolta SLR lenses.

That's the nice thing about modern mirrorless system cameras: You can continue to use older lenses that were intended for analogue SLRs by connecting them to the camera using a manual adapter. This works very well, you even have a preselection aperture facility, ie you only set the aperture on the lens, only when you take the picture do you turn the aperture locking ring on the adapter to the position - very helpful. I can only recommend using "old" analog lenses on the new mirrorless ones! I bought a Canon FD 50mm macro, an FD 100mm macro, an FD 35-70 and an FD 80-200 for a few euros and I am extremely satisfied with the image quality on the 61 MP sensor of my Sigma FP L, even with 100% view on the monitor. The lenses mentioned are sharp to the edge. This turns out to be a myth that analog lenses cannot be used digitally because the resolution of these lenses is too low. I can definitely recommend the K&F adapter. It is precisely manufactured and slides smoothly into the camera's bayonet.

The adapter allows the use of AF or MF Minolta/Sony A lenses on Sony FE mirrorless cameras. Very well done. The lens can only be used with manual focus, but is fine in most cases. There is an aperture slider that isn't marked with f-numbers but with click stops so you can count stops if needed. It serves its purpose and allows me to do some vintage reviews of Minolta SLR lenses.
