Neewer’s ND filter set is a great action camera accessory that prevents overexposure and eliminates glare and reflection.The kit is compatible with GoPro Hero 9 Black and Hero 10 Black and is composed of CPL, ND8, ND16, ND32, ND64 and ND1000 filters that are stored in a small protective hard plastic case. Each lens has premium 18-layer coatings that give a flawless appearance and reduce lens flare and avoid vignetting. Also, it is very easy to install, just unscrew the original filters in a counterclockwise direction and then turn the filter clockwise to easily change the filter.Upon using this, I must say that it works as it should, but it is not highly comparable to the branded ones. However, this one from Neewer is indeed ideal for beginner or amateur photographers. So far, I am very satisfied with its quality even though it doesn’t have that high-quality filter. It is ideal to use in capturing your adventures while travelling.With all that said, this filter kit is a of reasonable quality for beginners to intermediate use. Quality-wise, it is on par with the price.

I was excited to see this set of ND filters from K&F Concept. K&F is a very good company with a great reputation for high quality photo products, especially lenses and filters. The question of whether or not to get ND filters for a drone should be a non-issue. Without any trees and buildings filtering out some of the direct sunlight, you really need ND filters in order to get a good exposure. I think the 4 filter set that K&F put together here is a perfect beginning set; ND8 (3 stops), ND16 (4 stops), ND32 (5 stops), and ND64 (6 stops). Depending on your use and where you live, you may want to get higher and/or lower stops. I certainly plan on getting some more.In my area, it seems I have either water, snow or clouds that want to wash out my videos and photos. Even when it is overcast, which is frequent, I need something to get the details out of the sky. After many days of uncooperative weather, I was finally able to get some sample photos for my review. I tried to get photos of the sky without a filter and then with each of the 4 ND filters. But, I can't guarantee they will appear in the correct order that I uploaded them. So it may be impossible to determine which photo has which filter. Sorry...My only complaint and the reason for my review score, is they were an absolute pain to put on. It seems like the tabs that are supposed to fit into the locking slot is larger on these filters than the original manufacture's lens shield. When I looked at them side by side they appear minutely larger. As I tried putting them on, I thought I was going to damage the DJI lens housing, break a tab, or bend the slot it is supposed to fit into. The original DJI lens housing fits on snugly, but securely. These just fit on terribly hard. I think DJI is partly to blame. It seems like it would be easier for them to make the lenses so 3rd parties could make accessories that fit easier and securely (i.e., round threaded filter instead of square).In spite of that, these filters are very well made of high quality glass and materials, which is the most important thing for a lens filter. As the description says they are very light, nanometer coated, anti-glare, and waterproof and dust-proof. These will certainly be used a lot and I hope to see K&F adopt more of their lenses for the DJI Mavic 3 Classic. Please, just make the filters easier to put on. ;-)

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.

I don’t claim to be a professional photographer or even an able enthusiastic, but I have noticed this ND Filter improving my snaps. This filter is supposed to reduce the light coming into the lens of your camera thus allowing you to increase the exposure time. Now, my pictures have a more polished feel while offering a sense of life. But ultimately, unless my skill levels improve, this lens filter will probably be overkill for me. Well, at least for now.A high-quality piece of accessory that is aimed at the pros. It even has its own shock-proof case.

I am one of those photographers who keeps a circular polarising filter on my lenses full time. Recently I purchased a Urth Gobe 67mm for my 70-300mm F4L lens. Although this is a heavy zoom lens, I find that I can handhold it to produce photomerge panoramas. I wanted to see the effect I could obtain / create with a Variable ND filter. One word, OUTSTANDING. I was so impressed that I recently purchased a 77mm Urth Variable ND filter for my 20-105 lens. Haven't tried this one out yet but I am confident it will produce excellent results.The filters come in metal containers, the glass appears to be without any blemish or flaws.Delivery was as promised, so happy customer.

I tested this ND filter using my brightest pocket-size LED video light. I can say that this ND filter does an excellent job at reducing the amount of light that reaches the camera sensor. In my case, I've used ND filters mainly for outdoor video shoots. This ND filter has allowed me to keep the cinematic real-world motion blur by keeping my shutter speed at roughly twice my fps (that's a pretty good rule to follow).I used this on my Fuji X-T3 camera, and my lenses were 77mm in diameter, therefore I had to use one of the included adapters to mount this ND filter in front of my lens. The ND mount does not have any locking mechanism to keep the ND filter secure, so I'd say that that's not too great. However, it does have a tightening screw to secure the mount itself onto the camera lens, which is totally great.Either way, I'd definitely recommend this if you are wanting a high-quality ND filter and you know that an ND1000 will suit your needs! (Please consider using at some charts to determine how much f-stop reduction you need, this ND filter is NOT a variable ND filter).

This ND filter has its uses for example blurring the movement of waterfalls without over exposing the rest of the shot. Unfortunately for my use it is not dark enough. As I am just starting with experimenting with long shutter times I thought the range of this filter would be fine but I didn't really appreciate how long my shutter would have to be open for the light conditions I have and the effect I want. I really need a ND1000 (10 stops). That's not to say there is anything wrong with this ND filter it works fine is well built comes with a storage box to keep it well protected with an included cleaning cloth. I should have just read up a bit more before getting this as it's not dark enough for me.Something else to think about I couldn't get the lens hood on the lens after this was fitted.
