I’ve been using this Urth x Gobe variable ND filter for a little less than a week, and It’s been OK, not brilliant but OK and that’s to be expected for the price, there’s a little hazing and the colours can be a little yellow or warmer than others I’ve used but it’s also half the price of those, so it’s nothing I can’t sort out in post process. The dampening on the ring is smooth, a lot nicer than I expected and the quality of the build seems very good, it comes in a nice tin with a foam insert and a microfibre lens cloth and I get to feel good about myself because GOBE will plant 5 trees just for getting it, way to go GOBE.

This is my third order from Gobe and I will continue to use them for filters. This is my second Var ND filter the first was for my DSLR and this one for my GoPro setup. Both came package well with cleaning cloths they have performed as advertised, no color cast in my pictures or video.

I bought this ND filter specifically for my film camera. I love that Urth x Gobe makes products that are both suited and interchangeable with new and old camera technology. I haven't got film back yet but as I have the 77mm ND for my digital, I know the outstanding quality of the product and am eagerly anticipating and expecting to see great results!

Ich habe mir den GOBE ND-Filter gekauft, weil ich bei Offenblende, bei Tageslicht filmen möchte.Langzeitbelichtungen mache ich mit dem Filter nicht.Der Lichtdurchfluß lässt sich angenehm an der Vorderseite regulieren.Nachteil ist der Grünton, welcher hin und wieder auftauchen kann.Trotzdem gibt es von meiner Seite her eine Kaufempfehlung, siehe Video.

I had been meaning to buy a variable ND filter for my 24-70f2.8l for a while. When I heard about K&F filters; having tried a 3xnd filter kit pack that I was impressed with; especially at the price. I looked at K&F's other products and found this more than reasonable price ND filter and had to give it a go.The filter is shipped from China; so its not something to order if you are in a rush - but when it did arrive I was blown away by the quality of the presentation. The filter was packaged inside a well designed; expensive looking, cardboard outer package and then a hard plastic inner with a foam sheet to allow it some protection.On opening the pack one disadvantage to this filter immediately manifested itself; the front element isn't 77mm so your lens cap won't go back on the lens with the filter mounted. The filter mounted smoothly onto my lens. The variable darkness is achieved by rotating the front element; as you would a circular polariser. The K&F filter spun smoothly but with enough resistance to keep the darkness you set so knocking it won't change the setting. One disadvantage to the design is the filter doesn't have coded ND values so there is a bit of guesswork to get the right exposure for stills.I tried the obvious and took an image of a plain white wall at various ND settings; and there was some minor differences in the brightness of the photo - it was a bit lighter at the edges of the frames. At its darkest on long exposures; the 6d went red shift but this is correctable in Lightroom (and made much easier if you use a colour checker passport.) If you zoomed in on the plane white background you could see some variations in darkness; and ultimately pixel peeping at maximum darkness a mesh. That said taking pictures of something more interesting than a wall the effect was lost in the detail of the image.I rarely shoot video so for you dear reviewer; I shot some test video of the same white wall. I don't have any fancy video editing software and just watching the video back in lightroom; the darkening effect was pretty uniform across the photo. As with stills if there were any criticism it is very minor and that the corners show up brighter than the centre of the frame. The majority of the frame being uniformly dark. There was no patterning showing in the video.Using a standard ND filter definitely gave a more even darkness to stills but I am planning 3 long trips this year and carrying 5 ND filters everywhere felt like a chore. Now I just need one. If i could I would ding 1/2 a star for the front element size not being 77mm but its a minor inconvenience in the scheme of things.

Great ND filter for Rokinon Lens. Working as expected.

Got the Gobe Filter Kit 72mm MRC 16-Layer: UV, CPL Polarizer, ND8, ND1000 about a month ago. Since they arrived it's done nothing but rain. Eventually got out to try them and I have to say they did not disappointed. I am very pleased with the the photos as there is no colour cast like I was getting on the cheaper plastic ones. The only slight problem I got was when I knocked the lens and couldn't get the filter off. Easily solved by getting a small knife and running it round the filter where it screws onto the lens, pulls the threads even with no damage to either lens or filter... Happy Days!!

I have enjoyed using the 67mm filter. It does what it's supposed to.
