K&F Concept 77MM Neutral Density Lens Filter 10 Stops ND1000 Filter is impressive at this price range. I have used expensive filters that leaves noticeable color cast. But L&F filter leaves minimal color cast that is easily correctable in post-processing.On the downside, built quality is not as good as expensive filters such as B+W. Also I have noticed that it scratches easily. So as long as you are careful, it works well.I can recommend it to anyone looking for good results at reasonable price point.

On a very bright day, and when you need to control the light for a long exposure this ND filter comes in handy. Just make sure you use a stand, not recommended for hand holding due to hand shake. Over all it is quite good and worked well for me.

I was really excited to get this to try out long exposures.I open the shipping box & analyze the product for a sec, and think "hmm, K&F packaging is pretty nice, hopefully the filter is of as much value..." Outside box was sealed with a 'tamper-proof' plastic covering, inside the box is a nice hard protective case, so I wasn't expecting to find the filter petty much covered in particles of cardboard on both sides! Took my Rocket blower and blew the cardboard away, inspected for any visible scratches, couldn't see any (with my eye) but will inspect with a test pic tomorrow.In hand, the filter appears to be worth it's price, (the real test is in the pictures to come). Threads are clean, but I could not get them to mate up smoothly, seemed a bit sloppy when threading on, not as smooth as some other filters I have, my Hoya Triple Peak, is really smooth threading on for comparison.Will Update with pics soon! ...hopefully no scratches..
