It worked great on my Sony lens.

Perfect lens for the sony 28mm. Me a facilitado las grabaciones de video durante el día.

Arrived quickly. It was exactly as expected, fitted the camera perfectly and was easy to install. Lens hood and cap both fit as before. Ideal for Panasonic DMC FZ2000

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.

I shoot a lot of video with different lenses, and lately have been using my 24 f1.4 Sony lens quite a bit while outdoors, and this can be a very bright lens, so using a variable ND filter like this one by K&F can definitely be useful and a big help to shoot with low apertures and further blur out my backgrounds nicely. I didn't notice any real color shifting, and my image has remained sharp as expected. I like that this one is so variable and allows me to use just this one filter, rather than having to keep changing them out to different ones and the light changes. It's just more useful. I'm thankful this one came with that little plastic storage case, rather than a pouch or something useless, because it helps me to protect the filter when not in use. This is a nice inexpensive alternative to much more expensive ND filters and it's actually quite nicely made.

This adapter is used to use an A-mount lens on E-mount cameras (in my case a Sony Alpha 6100).
The construction is good, it weighs just enough to notice that it is a quality product, it works perfectly.

You have to keep in mind that with the adapter you will have to use everything manually, that is, manual focus is obvious, but something I did not know is that the adapter comes with a ring to close or open the diaphragm but it does not show the step diaphragm (1.8, 2.8, 3.5, etc).
In the camera as you move the ring it will not appear which diaphragm is being used either, specifically in my camera it says F/0.0, even so, you can use the aperture priority mode and the camera calculates the shutter speed without problems.

Works very well, I only recommend buying an additional lens hood because if there is backlight in the picture, it looks purple in the picture. Nevertheless, I am very satisfied, it does what it is supposed to do, I can't complain
