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 use these at work . I'm a welder they they are awesome. They stay charged all day.

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

Work as a welder. Comfortable and out of the way during my day.

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

Decent glass filter, very little green tint at 30 second exposures although for longer you might see more, either way should be easy to fix in post. It rattles a bit which is unsettling considering that vibrations on a long exposure will be pretty obvious, but its not that bad. I haven't stacked my circular polarizer on it yet, but it is possible. Overall, probably the best and filter in this price category. I was quite lucky to buy this one.
