there is no real comparison between pro-level filters, but if you are using a Variable ND filter or don't have one. This is a good entry point. An ND 1000 ( ND 3) Filter will give you the smooth water look you are likely looking for. There is minimal color cast. I do wish the case was a bit smaller. for 67MM or smaller, the case is larger than it needs to be. It arrived with no scratches and threads are fine. Remember the rule for every stop you need to double your shutter speed ( open longer ); ND 1000 is 10 stop you leave your shutter open 10 times longer.

The K&F Concept 67MM Neutral Density Lens Filter 10 Stops ND 1000 Filter Multi-Coated Optical Glass Neutral Grey ND Lens Filter with Multi-Resistant Nano Coating for Nikon Canon DSLR Camera fits perfectly on my NIKON lens, but is a very dark filter creating some light issues with my lens. the filter itself does exactly what it should and is expected to do though....but is very dark.

Purchased the 10-stop ND filter for the super-long exposure work I'm starting. The filter arrived on time as expected; there were some minor polishing marks on one of the filter surfaces (removed with a microfiber cloth), but no optical defects appeared in any of my test exposures. (And believe me, I looked for them!) I've purchased a few K&F Concept filters now and have always been satisfied...solid workmanship, optical quality is great and again, the price is right. I can certainly recommend this one.

The first thing I checked was the colour cast that this filter might impart and any effect on resolution. The lens used was a Sony 24-70mm f/2.8 GM, a very sharp lens at 24mm. I found practically no colour cast and no resolution loss, keeping in mind that the sensor itself undergoes some reciprocity failure during long exposures (it's worse with film).

I'm very impressed with this filter. I just picked it up and wanted to compare it to my B+W 10 stop...the difference is huge ! The B+W leaves a heavy purple cast that is not very easily correctable in post. This one leave a slight one but very easily correctable...and at a fraction of the price !Money well spent I would say

I was pleasantly surprised just how tact sharp the photos are with this ND filter being as affordable as it is. I shot in AWB "auto white balance" and did no color correction in post processing these images and was able to shoot at F22, ISO 50 for 30 seconds in the middle of the day with this 10 stop ND filter.

Love this ND filter and I will get more. You don’t have to break the bank for great results

Some of the Best Filters I’ve used! I was sent these filters to test and review but I will never review a product that I cannot give an unbiased and honest opinion on. I personally don’t do any photo or video work that would require such a deep cut off of light. But if you were doing work that included HARSH sunlight then this is the filter you need. It will cut down even the brightest of light
