To be fair, the falling off may be the lens - I can't tell. Basically it seems like there just aren't enough threads engaging. I am using it on a refurbished (by Nikon) Nikon AF-S 55-300 1:4.5-5.6. I have NOT tried any other filter on the lens.I have the same filter in 52mm and have used it on 2 other lenses (18-55 and 55-200) and it seems to engage more than this bigger filter in the longer lens.As long as you get it seated and remember to twist the filter orientation in the direction of tightening the filter it's okay. I got it backwards and ended up unscrewing the filter (which only seems to be less than a full revolution - less that one full thread) and it fell into dry sand. It doesn't look like it got damaged but I just don't enjoy using it because of the high possibility it may fall off again.And, it's hard to get the threads started.Again, I haven't used any other filter on this lens so it could be the lens too, which is more of a question because the lens was refurbished (although the threads don't look bad or as though they'd been truncated somehow).As for the pictures, I used it to effectively remove glare from a water body. It seems to work fine (as does my 52mm which I've used a lot more). No complaints but I may not see differences between this and a B+W anyway. I can certainly see the difference between this and no filter. I'd buy one again. I think the Tiffen's are a great cross between results and price. When I start seeing artifacts maybe I'll spring for a B+W or other brand.

A good quality filter is a must for any lens. This filter definitely has the high-quality I was looking for.

I was skeptical about this macro lens, because I had never used one on my iPhone and couldn't imagine that it could capture images of microscopic subjects. I like to photograph mushrooms, fungi, mosses and the tiniest details of flowers. This Xenvo lens does all of that with perfection. It's easy to learn, has two lenses, and comes in a handy, durable case. I recommend without reservation.

Filter looks fine, however the Canon lens cap for the camcorder did not fit very well on the filter, so I will have to get another lens cap.

Love the wide angle lens. Capture more of the video

I love this filter. It does exactly what it's supposed to. It also protects the lens.

I've had this camera since September 2021, and purchased it because I needed a decent webcam for work. It's not perfect, but for the price and the versatility it affords, it's great!I was able to use it for Zoom and self-recording (my main use cases), and on top of that I was also able to use it to capture some very hard-to-capture images and videos where I don't think a regular webcam would have worked the same.The lens is also swappable since it's a regular CS mount lens. I haven't yet put this to good use but I have purchased some wide angle M12 lenses that I plan on testing on it once I get some M12 to CS adapters for it.The USB cable is nice and long, though it is on the thick side, and the plug on the back of the camera is USB Type A, so it's quite big. That does make it more durable, but it also makes it a little harder to position. A right angle adapter helped my situation. It's now mounted to a friction arm on my desk so I can move it wherever I need it.The audio capture from it... well... it's not good, I'll say that. A separate mic will likely be much better. The lens itself also had some issues with quality, particularly with the little screws that keep the different lens rings for adjusting the zoom, iris, and focus from moving. One started to act up, and I wasn't able to adjust one of the rings properly (focus ring). Thankfully the seller was able to send a replacement. Final caveat: because it doesn't have autofocus, you'll have to play with the zoom and focus to get the focus right. I sit quite a bit away from the camera, beyond arm's reach, so I've had to adjust it a few times before I locked it down. I wanted to get an autofocus lens for it, but I'm not sure how I would set it up (all the autofocus lenses I've found have an extra plug, and there's nowhere to plug it in on this camera body).If you're looking for a great camera and don't need autofocus or a mic, I highly recommend this camera!

I have been using this filter to protect my lens and it has done the job.
