I don't normally write reviews but this K&F Concept filter is really great. I was just expecting a random black filter with blue stripes to come in a "meh" case, but this one really upped its game and has a blue metal ring. Definitely recommend using it for music videos where you want the production quality to be much higher than the budget.

The filter quality seems to be perfect. I'm used to that from K&F Concept. And you get a really nice blue streak effect. The problem, however, is that you get that with every single light source in your image, so you don't really have the ability to be selective. You have to compose your recording really carefully. The filter rotates smoothly, allowing you to change the direction of the stripes, but you'll still see them in any light source. I think in the end Photoshop is probably the better option to give you more control over such effects. Still, it's a worthwhile tool to have in your toolbox, especially given the cheap price for an FX filter. It uses the same high quality optical glass as the other newer filters. The precision machining of the filter threads and ring is impressive and gives the feel of a much more expensive filter. So I can't fault any of the properties of the filter. It's just for the way I shoot, it probably won't be as useful as for some other types of photography.

Very good 77mm blue streak filter. The blue steaks can be rotated 360 degrees, which means you can point the light spots in any direction you want to create some very interesting effects. The images I've added are an example and were taken in the same spot I just rotated the filter to show how it works. So far I haven't had any issues with removing the lens filter that you can get with a rotating filter. I'll admit I didn't quite understand how this would work and tried using it during the day on a cloudy day and obviously didn't get anything, but I can confirm that this filter does the pictures I took has not affected, so you can put it on your lens and as long as there are no lights, everything is fine. For this to work you will need a light source, street lights, car headlights, wall lights, etc. BUT note that you cannot choose the light source. So if you have multiple lights you will get the flare effect on all the lights. I tried this on an 85mm lens and with the lens filter on I was still able to attach and detach the lens hood as normal. The filter doesn't have an overhang on the lens, but that probably depends on the lens you're using. Overall I am very happy with the Blue Streak Filter and would recommend it to anyone wanting this effect.

did some portraits with this bad boy and they turned out pretty cool. It has this soft glowing look that I've seen many times on IG and now I feel fulfilled because I can create the same look. I feel like I rose by starting experimenting with filters. I will definitely always have this filter in my bag. 10/10 I would recommend

This little beast of a filter has been my favorite new tool for my last few video shoots. This makes my job easier because now I can make a rapper or artist look trippy without visual effects. It also feels very heavy. I had never spent that much money on a filter before, but this one was definitely worth it. I will update this review if anything changes.

Neweer does a lot of very cool things about photos. This filter has a very narrow functional focus, but what it does it does well. Old-school photographers love the challenge of capturing the best photo with the effects they want, without having to touch Photoshop. The lens is of high quality and fits my lens easily. Quality threading I wasn't worried about and an awesome light burst effect. The finished effect can be angled at different angles by tightening or loosening the lens. Another cool Newer accessory for my gear bag!

got this prism last week and as you can see from my example photo it works amazingly well! It is easy to apply to the lens and creates an incredible effect! If you are interested in concert photography, I would definitely recommend this!

I've been looking for something to spice up my recordings lately. I'm tired of boring looking frames. I rolled the dice on this filter and in the end it was just what I needed. I love it

Given the current interest in anamorphic lenses (and the effects they produce), it's nice to have a reasonably affordable option to recreate the most commonly desired effect (streaks of light) without buying and learning a complicated/cumbersome anamorphic setup need to use effectively, or spend a lot of money on one of the newer modern anamorphic lenses. The build quality is good, perfectly functional and in line with what I would expect at this price point. This filter is a very specific creative tool that I will use in very specific situations to achieve the desired effect. I won't be using it on most shoots, but being able to pull it out on the shoot I need it for will be a huge benefit.

Best quality filters out there... at this price point it doesn't get any better. It's so much fun to use and adds a cool personality to photos. Definitely a must have in your camera bag.
