K&F Concept 67mm ND8-ND2000

I've been using the K&F Concept 77mm ND8-ND2000 Variable ND Filter on my Sony FX3 setup, and it has become an essential part of my kit for shooting outdoors. The adjustable 3-11 stop range gives me plenty of flexibility when filming in bright sunlight. It allows me to maintain my preferred shutter speed and aperture for cinematic footage without overexposing the image. The rotation is smooth and easy to adjust while shooting. The optical quality is impressive for the price. Colors remain natural, and the image stays sharp throughout most of the adjustment range. The 24-layer multi-coating helps reduce reflections and makes the filter resistant to water, dust, and fingerprints, which is especially useful during outdoor shoots. The slim frame also helps prevent vignetting on my 77mm lenses. Pros: Wide 3-11 stop adjustment range Good image quality and color accuracy Durable waterproof multi-coated glass Smooth rotation mechanism Lightweight and easy to carry Great value for money Cons: Like most variable ND filters, it's best to avoid using the absolute maximum setting to prevent potential image artifacts. Overall, this is an excellent filter for videographers, photographers, content creators, and filmmakers who need a versatile ND filter without spending a fortune. For the price, the performance and build quality are outstanding. Highly recommended for Sony, Canon, Nikon, and other camera users shooting outdoors.

I am using this with my sigma 16mm lens and Sony A6400 so it’s work perfect so recommend to all

Very good

I bought this filter. Abd, I used it on my trip to Turkey; when I returned and downloaded the photos, all had black spots on the side of the images. It's very cheap quality.

The quality is bad, not good for long exposures as well vineyard very clear. Weird color fringes in the images which is unable to recover during post production

Great tool for getting proper exposure in broad daylight. Really loving the stop reduction range and I haven't noticed any color shift. There is one thing to note: the last two stops introduce vignetting and it's pretty noticeable but it's an easy fix just buy a fixed ND (NDs 8-64) and stack this on top to use lower stops on this one. It doesn't take away a star imo and I appreciate this sm as it allowed me to stop worrying about gear and starting documenting my life with my wonderful camera. I definitely would recommend this to anyone starting out videography as it's easy to use, affordable and long lasting thanks to its metallic build

I was skeptical purchasing a filter that was on the cheaper end, and boy did this deliver! Bought for a vacation to capture long exposures in direct light and it works great! Adjustable apature ring, highly recommend!

Very super

Versátil y su empaque sólido

I wanted to be able to shoot off camera flash without having to use HSS (high speed sync), so i did a little research and came to the conclusion that I needed an ND Filter. There are a lot of options out there but I knew the price point I was comfortable staying in and this filter was the best blend for versatility (3-11 stops) and price. I didn't see the benefit in getting an ND filter with a smaller stop range such as 3-5 or 7-11 etc. This ND filter covers the entire range in one package. And the adjustment ring feels high quality and has really good feedback when stopping down or up. I saw some people complaining about the grid pattern you get sometimes when stopping down on other ND filters, but I haven't experienced that problem. This ND filter has been nothing but perfect for me. I was able to shoot at 11 AM with with harsh light and overpower the sun with my flash for a recent shoot while staying under 1/250 sec. I definitely recommend this ND filter if you need to stop down for whatever type of photography you're into. The only issue you may have with this ND filter is trying to use a lens hood with the filter as they may not fit with one another.
