Impressed with the photo quality using this filter... I've got a very critical eye when it comes to color cast using ND filters, and there is NONE. The fit and finish of the filter is also very good... I've had color cast with more expensive (different brand) filters.... I give this 2 thumbs up and I'm going to stick with K&F Concept from here on out... GREAT BANG FOR THE BUCK... can't imagine why you'd spend more... ZERO COLORCAST IS ZERO COLOR CAST, whether you spend $30 or $130.... Buy this one! And spend your savings on other equipment!!

I just received this (52mm, for a Nikon 50mm f/1.8 on a D600) and it looks solid.
Initially, I had some trouble with the exposure. In a setting where aperture priority gave me 1/100s (w/o filter), I expected to get 10s shutter speed with the ND1000. However, the camera came up with ~1/5s - and the photo was almost black. It took me a while to figure out that the metering was affected by light coming in from the viewfinder. Once I covered that, the images were well-exposed (and I got the 10s, as expected).
I hope this saves others some time and worries (one hour in my case, plus the fear of having wasted $28 and not being able to understand my camera...)

To smooth out water in waterfalls or creeks, you need 9 or 10 stops of ND. The VND filters that go up to 400 are not enough.
