I always wanted to get into long exposure photography and new I had to get an ND filter to do it properly. This lens had hundreds of reviews already so I figured it was worth a shot.BUILD- The quality of this lens is great. It is metal, and is much heavier than I thought it would be. I don't know if all ND filters are as heavy as this.FILTER- It's rated as 10 stops. I don't know how to confirm if its exactly 10, but it does cut out a ton of light. It does it effectively. I didn't experience any vignetting, but I wouldn't consider any of the lenses I've used as "ultra wide angle" either.PHOTOS- Color is great, the photo I have shared speaks for itself. I'm about to go to Utah and will take additional samples.

This is a true multi coated glass ND filter and works just like you would expect. Yes, it IS actually glass as opposed to the cheaper plastic / resin filters. The multi coating effectively reduces reflections, which you can verify by looking at the lens like a mirror since it makes bright white lights reflect as dull green. There is no strange color cast and images are just as sharp as without the filter. I don't notice any more reflections or flare when using the filter but I do see slight vignetting at wide angles and large apertures (17mm f/2.8). Even though ND1000 is a 10-stop filter, I had to adjust by 10 1/3 stops to match the exposure of an image without the filter, but that's okay because it's easy enough to compensate.WAY better than the cheap plastic / resin filters you get in cheap kits.(FYI, I Bought this on 'the Bay' from seller kf_concept_us and it shipped from China for about half the Amazon cost.)
