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

I brought these lights for my green screen and they work perfectly! The orange tinted filter is a little too much so I use wax paper over these lights with the STD white filter and it softens the light just like I want it! I recommend it on a budget! The plastic seems cheap so when I took the feet out I kept the feet out.

Great value for a ten-stop ND filter. There is some green fringing, but it is easily corrected if you shoot RAW files. Love using this for daytime long-exposures.

I took these shots with and without filter, difference is very huge. The more green one is with filter and other is without
