Fits the Sony VFA49R1 Filter Adapter with a filter inserted. I wish it had an option to connect some type of lanyard to attach to the extra lanyard hole on the camera, but unfortunately it does not. You can find ones on Amazon without the Sony name printed on it for cheaper, but if you want one with the name this seems to be sturdy and of good quality.

I haven't actually attached this Neutral Density filter to my smartphone yet because I haven't received the adapter that I ordered to attach it to my anamorphic lens, but I've dealt with so many accessories that I don't need to.Simply put, this accessory will do what it says. The rotating ring has very smooth action and has the feel of a very solid build. Being an adjustable neutral density filter, this accessory allows you to fine-tune the amount of light that reaches your camera's sensor so you can shoot with a fully-open aperture without fear of blowing out your image or video. This is a 52mm nd filter, so if you're shooting with a DSLR with a 52mm attachment threads, this will work for you if you're not going the smartphone route like me. If you are using a smartphone you'll an adapter.All-in-all, great piece of tech for the money.

Having just bought a new lens that had a filter size different to any filters I currently owned, I was interested to see this Neewer 58mm set which provides all the basic filters.Even though the set is 58mm it could be used on lenses with a smaller filter size if desired by using an adapter ring. Such rings are not expensive.The set consists of a UV filter, a CPL filter, and four neutral density filters - ND4, ND8, ND16, and ND32. What is interesting about this set is that there are two adapter rings that allow the filters to be used on GoPro cameras. Along with the two provided lens caps all the filters and adapters fit into the provided storage case.The listing states the adapters and filters are compatible with GoPro Hero models 8, 7, 6, 5. As I have a GoPro Hero 8, this was very much a case of killing two birds with one stone as the saying goes.In use the filters all screwed on to my new lens without issue. The filters are slimline and as such are a little fiddly to install but they did all fit with a little bit of effort on my part. The filters also screwed into the GoPro adapter without problem as well.I found the CPL filter to be a little stiffer than I personally like but after ten minutes turning it loosened up to where I was happy with it.I have other Neewer products, and these filters are certainly up to their usual standard. Considering you are getting six filters, two adapters, and two lens caps, for this price I would recommend the set to anyone looking for an affordable basic set

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.

Using a 2x lens adapter and a moon filter we had a great view of the full Moon and Lunar Eclipse! This was easy to set up and just as easy to learn to use. Well, I didn't do a Polar Alignment and we just blindly pointed at the objects we wanted to see. It worked out perfectly! :) I HIGHLY recommend this scope as a beginner scope and look forward to seeing what she can do once we are not under a street light.

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.

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