This is a quality filter. The threads are firmly connected to the camera lens and the resulting images will not be distorted when this is on the camera. I love the double sided flare that gives night time images with a light in the middle. I've always wondered how photographers do it. Now I not only know how, I also know how easy it is.

Apart from the blue stripe effect in the lens, the glass is very clear. I can't tell much of a difference when it comes to image quality with the filter off and on.

The filter only seems to take effect when the conditions are right. I pointed it at really big bright objects and it doesn't seem to "prob". With smaller lights it comes into its own much more. Or maybe I'm just crazy.

Such an impressively organic look. Absolutely obsessed with this thing and super excited to add it to the gear!

I tried it on my last shoot for one of the biggest brands and it worked perfectly! helped me make the place look more interesting and have the focus on the topic!

It is a bit difficult to work with such filters as not every lens gives unique results. However, when you hit the mark in combination with the right lighting, it works so well.

I also got the anamorphic filter and can't wait to use it on a new shoot!

Other points worth emphasizing: I have invested heavily in the competing brand prismlens fx; I own almost every filter but one thing they are missing is the 82mm filter and K&F Concept hit the spot by offering their filters in 82mm. A reduction from 82mm to 77mm presents no problems, whereas 77mm to 82mm creates a lot of vignetting.

If you use it during the day, there may be some unwanted flare on the lens.

This streak filter can be rotated up to 360 degrees and is perfect for creating differently angled and dynamically rotating flares.

The anamorphic streak filter from K&F Concept creates a cinematic vintage effect on photos and videos by transforming points of light into linear anamorphic light reflections. It has a 77mm camera lens with a mounting thread. With an adapter ring, a step-up ring or a step-down ring, it can also be used for camera lenses from 32mm to 82mm. It is equipped with 8K Ultra HD optical glass, has 28 nano-layers and low reflectivity that ensures high-resolution photos and video recordings.

It is lightweight and consists of an anodized aluminum alloy frame. It has an ultra-thin frame that reduces vignetting and dark corners when mounted on a wide-angle lens. CNC machined and anodized aluminum alloy frame is built to last, abrasion and erosion resistant. In addition, the trapezoidal pattern on the frame is ideal for easier grip and non-slip function. The filter is excellent because it is waterproof and oil resistant.

I like the fact that the lenses can be rotated to adjust the angle of the spread. Also, the brightness and intensity of the filter will depend on your setup and the light you're shooting. The compact effect filter comes with a filter box and a cleaning cloth, making it efficient and practical for your recording and filming.

All in all, this is a great product that allows me to be more creative in my photo shoots with less effort.

I like that the filter is well built and made of good clear glass. It's interesting to play with the effect... you can get really extraordinary shots. The price is good for the quality... good value for money and a nice filter in your pocket

This filter has limited uses, but if you want to get a little creative with your photography, this filter is for you. Once you've attached the filter to the end of your lens, you can rotate it a full 360° to place a blue stripe at any angle.
As with other K&F Concept filters I have, the quality is there. It comes with its own hard case and lens cloth.
It's not the cheapest filter, but I think it's worth the price.

You need some good, sharp highlights, e.g. B. if you point it directly at a bright light to get the most out of it. When you do that the effect is great and it's good at mimicking the blue streaks you get from anamorphic lenses. You can rotate it to any angle, which is handy for switching between portrait and landscape modes, but anything other than horizontal stripes looks odd to me. Probably just because we're used to seeing that in movies.

Aside from the blue stripes, it's otherwise very clear and hardly detracts from the rest of the picture, which is great.

This Blue Streak filter comes in a beautiful K&F Concept branded cardboard box (sealed in a plastic wrap). Inside the box is the filter, well protected in a handy protective case. A small cleaning cloth is also provided.

The 77mm diameter frame of the filter is well made and feels quite sturdy. It screwed my lenses and step-up rings on and off with no problems. It also rotates smoothly so you can change the angle of the flare effect to your liking.

The quality of the glass is also very good without any significant problems. Due to the thin frame, I didn't have any problems with vignetting either.

The Blue Streak filter effect is great for recreating the Anamorphic Flare effect. In this case, flare from a light source appears as a stretched horizontal line, rather than circular bokeh. With care, this can really add impact to your image and can also be used to give your image a different mood or atmosphere. It's a useful effects filter whether you're shooting, filming, or both.

In summary, this is a well-made filter for adding anamorphic flare effects to your photos and/or footage. While it may not quite live up to the standard of far more expensive filters, unless you're a professional filmmaker who needs the absolute best, it should be perfectly good enough for what you need.
