Great lens filter at a good price. I didn't notice any blue tint or reduced image quality.

The UV filter has a high-quality and clean finish. I really like the blue-purple reflection and it really makes a difference. I didn't notice any changes in image quality, but there could be a slightly different, increased lens flare. If you like the look, you will be satisfied with the filter. In any case, I can recommend it as protection for the lens!

small disclaimer: I'm not an ND1000 filter person, I find their water/cloud smoothing effect mostly unnecessary and overdone, overused and overpowered (and many more overs). I said that I need a little more than ND64 every now and then, so I decided to give this KF a try, especially since it came in at 40 EUR with a Black Friday discount. I didn't expect miracles and was prepared for severe color casts. It turned out better than I expected. With this filter there are obvious color casts (photo 1) and to all the claims of "I don't see any cast" all I can say is turn off the AWB please how else can you talk about color casts seriously?! but with the WB adjustment it corrects (photo 2) very close to original colors without this ND1000 (photo 3). Correction scale: 5000K->7200K and 0->+35 magenta in Lightroom. As expected, the sharpness for a wide-angle lens (35 mm) is perfectly fine. I do notice more vignetting (both lenses have the same degree of lens correction), which I'm not sure how to explain, but I personally don't mind, some in landscape shots. Overall I'm pretty happy. It's a cheap alternative to brands already known for heavy blue casts (love your ND graduates, Lee, but your Big Stopper is pure and simple a blue filter, period) and for casual use, you really can't do more expect

tested it out in my house and on the grounds of my building today and had some excellent results with it. It blocked out glare in puddles and on windows, improved contrast shots across a rain-soaked driveway, and produced an intense blue sky from a fairly washed out light blue sky with thin clouds. The filter construction is very high quality, the threading feels positive and is neither too stiff nor so loose that you'd fear it'll come off. The rotation of the polarized display is a little stiffer than I'd like. A couple of times I found that when I was past the ideal level and wanted to back off a little, the filter unscrewed. I don't like tightening filters too much, so I'm hoping it will loosen up a bit with use. It comes in a sturdy, if slightly bulky, plastic box that I replace with a more compact filter case when I'm out and about. Also included is a lens cap and lanyard. I don't remotely like the lens cap, the front edges of the push buttons on each side are sharply bevelled and they have no grip so if like me you have quite dry skin it's not easy to hold onto, in fact I dropped it twice within minutes of opening the pack so I found it quite funny when I saw the little video in the advert which was expected to just extol the virtues of the filter only to find out it was actually just about the cap and that the lanyard is there to stop you losing it. In over forty years of using SLRs and DSLRs I have never come across a lens cap that was less suitable for an active photographer on location. Lens cap aside this is a great filter, it does everything you'd expect from a product that's priced far higher than the £13.99 it currently costs and should last a couple of years if looked after. Perfect for beginners or experienced photographers and incredibly good value for money. What's not to like.

This kit comes with all the filters you will likely need. The UV Filter is one you will keep on your lens to protect it from accidents. The other filters, Polarizer Filter and Neutral Density Filter are more specialized. The Polarizer Filter is basically used to reduce glare from reflective surfaces and make blue skies "more blue." The Neutral Density Filter basically balances exposure in high contrast scenes. Note that you never get something for nothing, and your mileage may vary. The set also comes in a nice storage case. I bought several of these sets and I highly recommend them.

UV filters in the digital age only make sense to a limited extent. I mainly use this type of filter as a protective glass for the lens, so that I don't have to worry about damaging the lens even on the beach or during somewhat hectic photo shoots. The protective function is achieved very well with this filter. The processing is good, the glass is clear and without inclusions. The filter edge is thin enough that there is no vignetting. The blue coating is a bit annoying. If the sun hits the filter unfavorably from the side, a blue shimmer is produced on the photos. Of course that shouldn't be the case. However, this phenomenon only occurs at very specific angles to the sun. But the value for money is good, so ⭐️⭐️⭐️⭐️

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.

had fun playing with this Blue Streak filter. It creates blue stripes on your subject or, depending on the setting, light stripes. I enjoy capturing unique shots with the camera and this one is really great. It rotates 360 degrees on your lens, allowing you to rotate the strips in any direction. I have always been satisfied with products from the K&F Concept brand. The filter was clean and ready to use, which is a rare treat. It also comes with a durable carry case and microfiber cloth. Very happy with this filter.
