The K&F Blue Streak filter does a great job of getting that Spielberg light flare. Usually it shows up when a character opens a door and the light dramatically blooms in from the dark. This filter worked on my iPhone as well as my DSLR.
The 58mm fit my Samyang prime lenses snugly. The filter is well machined and allows the axis to pivot, making it easy to point the flares.
The attached photos were made on a 24mm and a 75mm. The effect adds a dramatic element to the shot.
Want to note the 58mm filter comes in a large filter holder. I prefer smaller filters in a smaller holder so I can keep it in my pocket. Just some nitpicking.
The filter performs well and is easy to use. I am impressed once again with a K&F product.

It offers a unique effect that adds a touch of magic to my photographs without overpowering the scene. The craftsmanship of this filter is top-notch, demonstrating great attention to detail. Its user-friendly design allows for easy attachment, and with a bit of experimentation, I discovered that the filter's angle adjustment feature truly brings out its full potential.

One aspect I appreciate about this filter is its subtlety. Unlike star filters that create bold, pronounced effects, this filter produces a more delicate and nuanced result. It adds a certain charm to my images without distracting from the main subject. When used correctly, it can truly elevate the overall aesthetics of a photograph, giving it an artistic touch.

The filter's construction is solid, and it feels sturdy in my hands. The ease with which I can simply attach it to my lens and start experimenting is a definite plus. All it takes is finding a bright light source, adjusting the angle of the filter, and watching the magic unfold. The filter delivers a nice effect that enhances the visual appeal of my shots.

In conclusion, this lens filter is an excellent addition to my photography gear. Its quality craftsmanship, subtle yet captivating effect, and user-friendly design make it a standout product. If you're looking to add a touch of enchantment to your images, this filter is definitely worth considering.

I got a new camera, because I wanted to try doing more videos. I was looking for a special effects filter that could add an artistic flare and decided to start with this filter. This filter casts a blue streak or light flare at different points of light in your photo/video. In addition, the outer ring of the filter can be rotated so the angle of the blue streak can be altered 360 degrees. I am still experimenting, but so far I've noticed that on bigger lights, the streak appears like a beam of blue light. Then in bright sunlight, the streak appears less blue, almost white.

This filter is made of high quality optical glass with multiple layers of ultra-thin, nanometer coatings and ultra-light materials. The frame is very light and thin compared to some of the other filters I have. In my first few experimental photos and videos, I feel this filter has a lot of potential for portraits and still-life, as well as videos too. I also feel the price for this filter is very good and is a very good value. I highly recommend this camera filter for anyone shooting photos or videos and wanting to add an artistic element.

One of my favorite stylistic filters for concert photography or music videos. It just adds a nice natural flare to your scene. No vignetting or weird distortion to your image. It works for me

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.

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.

I 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 filter adds a little pizzaz to lights, adds a little interest. it came make the scene too cluttered though if you have a lot of lights. Also, the streaks tend to to curve away from the center of the filter, so if you have lights off the to side this can possible detract from the image, though it is not bad.
the filter rotates to get the lines in the direction you want. but as noted in the another review because of this it can be difficult to get it off another filter. I would recommend not using with a UV or another filter.

This filter did some amazing things at a night time car meet - will attach some pics:

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!
