[Multi Coated] For the money, I think this is a great filter. I particularly like the fit and finish and that it is very thin. I use it on one of the new Hasselblad X lenses and it's perfect, unobtrusive.

[Multi Coated] Crystal clear glass set in a finely milled metal casing. The filter's fit and performance is unbeatable.

[0.135 lb] Used it on a normal nighttime city shoot. Worked great. No color cast. Quality materials. Recommended.

[Glass] I have had the Lee Filters NDs for several years, and after trying Haida's 6 and 10 stop filters I will not go back. The Haida ND filters have a more natural color balance then the Lee. I had purchased their filter holder system as well but I didn't like it and kept my Lee holder system. This filter does work in the Lee holder though it does fits very tightly, not necessarily a bad thing as it is light tight. I am very pleased with these filters!

[Multi Coated] I bought this filter specifically for astro photography . I am not an expert in the field but the filter works. It removes the orange glow from the street lights and allows for better pictures while maintaining relative colour accuracy. I am using it on sigma 30mm art.

[Multi Coated] perfect filter for the Nikon Z 14-24 f2.8 not so expensive

[0.135 lb] After going through the reviews and comparisons, I decided to go with the Haida Clear Night filter. I bought the 67mm for use with my Sony 24mm f1.4 GM. First test was at Ft. Griffin which is a very dark site but you still get some light pollution on the horizon. What made me a believer in this filter was when I a couple photos, both with and without filter, as I was setting up. A quick view in the evf showed a dramatic difference between the two shots. As some have said, you do get more blue cast to the night sky, but I really like that look. And I can warm up whichever elements I want should I want to do that. All told a really nice LP filter. I liked it so much I purchased a 77mm version for other lenses.

[Multi Coated] I ordered this to see if did more than the Kase polarizer I have. It does. I like it more also because the magnet is strong enough for it not to fall off but also allows you to adjust the pola (turn it) without trouble unlike the Kase filter. So for me I like this buy and would recommend it. It is also worth noting that prior to needing a magnetic filer I only bought B+W filters for the past 15 years so this was going out on a lim but it worked.

[Glass] Great filter at a reasonable price.

[Multi Coated] I test it and check the file quality is perfect
