This has worked great for me so far. I am using it on my canon 50mm 1.4 paired with my Canon SL2. It’s nice that it has little indicators so you know the filter position before shooting. Didn’t get the “x” shadow like some people did, even on my 18mm-55mm.

This product arrived super fast and is exactly what I wanted. Great value for money, and I would absolutely recommend this to my friends.

For the price this is a great nd filter, The only downside is that you get a slight green colour cast but nothing you can’t fix in post production, otherwise great filter.

This filter is the bomb! I use it in broad daylight to slow down shutter for that cinematic look. My videos have been coming out nice as of lately. This is actually my second time purchasing this same filter for a different camera. Highly recommended for those who want to master their camera & shoot only in manual...

Does exactly what they claimed. However I was ordering a polarizer, but I'll keep this and go again. Pleasant surprise.

Damn good filter. I shoot a lot of video and I highly suggest this ND filter. It might be better than my $130 Hoya ND filter. Great product!

One of the greatest Variable ND filters for its price range.Of course, If you are looking for Zeiss grade accessories, pricewise it will cost you something 10x times more and when talking on such precise and high grade attachments for your lenses, Variable ND filters are not the options - you should have bunch of fixed ND filters, with finest and highest grade glass and coating.This one does same if not more as similar Variable ND filters for $50-70, Slim design, so if you stack it on top of standard protective UV filter, it doesn't generate vignet.Glass is fine and high grade - no significant distortion for most $700-$1200 lenses, which I think is not bad, comparable to lens distortion values itself. Again, if you are such picky for distortions and using Zeiss Otus or even Milvus Primes for over $3000, then you should afford getting fixed ND filters from same Zeiss :)If you have DSLR, your backpack is almost heavy enough, so instead of carrying bunch of fixed ND filters for regular outdoor shootings (and weather is coming up and more bright sunny days we'll have :) ), Variable ND filters are desirable lens attachments and for most of APS-C and Full Frame cameras with sensors common 24 MP sensors, this one is one of the optimal solution.BTW, after great medium range tripod from K&F Concept, this is another camera accessory I've got and I like both - great manufacturing quality, nite and clean, functions as it should be and excellent Price/Quality ratio....

This filter creates a really bad vignetting. I do not recommend this..EDIT - I was able to get a hold of customer service and they explained to me on why the vignetting was occuring and that it was a easy fix. Thanks!

Almost everything I could say about this ND filter is positive. I bought for my slr magic 35mm lens and it does the job. The only thing the case it came in was slightly cracked but the product was in fine condition. Especially since I live in a very bright location this will help shooting during the day. (would've been 5 star if not for the cracked case)

Amazing filter for the price, We don't go anywhere without it.
