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.

Fits our Fujifilm (FinePix AX655 - 16 Megapixel Digital Camera with 5x Optical Zoom) perfectly and has a lot of padding, which will definitely protect if the camera is dropped.

Case is very good in quality and design. Fit perfectly on my Fujifilm finepix XP200 camera. have one additional pocket to put extra battery and SD card. totally Love this.

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.

Perfect fit for my new Fujifilm FinePix AX650 16MP Digital Camera with 2.7-Inch LCD (Black). And I like the long strap for hanging around my neck. There's plenty of padding and space for an extra memory card.

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

Love this product. I use it together with the Pro Pad v2 for comfort - to hold my Fujifilm X3 with any lens (I have the kit lens and zoom 200 mm). I like my hands free when I'm walking. Feels great and very secure on the front of my belt. Clip on and clip off is simple and efficient. Plate on camera body is solid. Only minor scuffing on black paint. As expected Peak Design offers great products. Highly recommended.
