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.

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.

I ordered the 52mm filter because the 30mm f1.4 sigma lens for sony e-mount cameras has a 52mm thread but after lens arrived, I couldn't fit it on.But after-service support was pretty helpful in telling me this

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

I bought this filter for my Tamron 17-28mm e-mount lens and love it. I haven't noticed any major color distortion and the sharpness doesn't seem to be affected at all either. The low profile seems to negate most vignetting you may encounter, but it does show up (unsurprisingly) if you stack this with another filter like a CPL. The gold ring is a nice touch too. I would absolutely buy these again as you get great results for the money.

I usee this filter with my tilt shift lens,amazing filter and value
