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.

This filter is very interesting. As stated in the product description, it mimics the flare of an anamorphic lens. However, this effect comes with some caveats.

First, this filter creates this effect using small lines of a blue diffusion-like material. That gives you an anamorphic look, but it tends to overdo it. Flares are much more solid than a true aspheric lens and become unusable in locations with many large light sources. However, this is better than buying a $2000 Sirui lens unless you have two grand sitting around.

Second, since the filter uses physical material to create the effect, it's easily visible when you're looking for it, otherwise it disappears in the image. In my experience, this side effect worsens with longer focal lengths.

Third, because the filter uses a physical material to mimic an anamorphic lens, autofocus sometimes gets muddled. I used this filter on my Sony A7IV with a Sigma 24-70mm 2.8 lens. At around 24mm, the autofocus would occasionally go haywire. Again, longer focal lengths exacerbate this problem, especially when focusing on subjects closer to the lens.

Pros: This filter is very cool despite the caveats I discussed. I used it in a short film and I loved it. is it perfect No, but nothing ever is. If you are looking to buy this filter I would recommend it. However, if you have a few thousand dollars burning a hole in your pocket, buy a true anamorphic lens like a Sirui 100mm. Overall a great purchase I have no regrets but be aware of the issues involved. If you want to use a fisheye lens: maybe not for you. If you want to get very close to a topic: Not for you. If you want to shoot in dynamic lighting with a longer focal length: this is for you.

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.

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.

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.

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.

I was looking for filters that would offer a stylistic boost while maintaining image quality. I came across this filter and decided to give it a try. Great price, fast shipping and a company that really cares. take my money Over time I look forward to getting more of their filters as well. Try this product.

Not only did this filter provide the flare look I was looking for, but it added a cinematic softness to everything captured through it. Streaks are really noticeable with extremely bright sources (like the sun), but you can get some great effects if you light them acid-free like I did with an LED flashlight
