Easy to install, packed with extras, and looks great. It's fun to see how this blacks out an IPS LED screen with a filter, but doesn't change anything on an OLED screen on a first test. Rotating the CPL is silky smooth, and given how great live view is on mirrorless cameras, it's just so nice to use filters now. Build quality is great, and the nano size is always a plus. I currently have it on a 77 to 82 step-up filter on some older glass. Since I'm moving from EF to RF glass, I've had to replace some 77mm filters with 82mm filters. This CPL is just right for reflections and just anything a CPL is generally useful for. I like the lens cap they give you for it. The pinch design matches many of the newer covers currently available for OEM lenses.

Great little filter made specifically for Cinematic effect.
I'm a professional photographer. I had written a rather lengthy 5 star review, but it was rejected for reasons I am not aware of. I recommend this filter if you are looking to soften the visual impact of your photos and video.

I ordered this to put in my daughters car for our cross country trips and I am very pleased with it. I am so happy that it came ready to install, plug in and use. The screen is small but it's clear. The rear camera area on the screen is really too small to use. The user manual is completely useless.

I use the 77mm filter on my Canon EOS 6D with a standard 24..105mm lens. He fits there perfectly.

In the test photos, there was no visible difference on the camera screen from photos without a filter. The effect only became apparent in the details on the big screen. Otherwise very bright areas are reduced in intensity by the filter and sharp edges are also softened a little, but without the kitschy effect of a soft focus. If you take a closer look, the entire image is somewhat darkened, as if by a very fine gray haze. The differences are almost imperceptible in normal ambient light, but are visible on the screen in dim light.

I like that the filter gives you more atmospheric pictures, especially in dark surroundings with light sources in the picture (e.g. candle, lamp, moonlight on water, etc.), without having to post-process them heavily on the PC afterwards. The halo around the light sources is visibly emphasized without appearing artificial.

This diffusion filter is certainly not intended for everyday photos, but rather for special moods. Of course you can still edit the pictures on the PC, but the filter does some of the work when you take the picture and - as I said - doesn't look so artificial. Therefore, amateur photographers who like to work with atmospheric light should at least take a look at the K&F diffusion filter.

K&F has been making some really fantastic filters lately. The build quality of these devices is excellent. Precision machined brass rings thin enough not to interfere with the image but strong enough to protect your glass. They screw on very easily and the brass prevents unplugging and threading. The optical quality of the glass is excellent. There is no distortion whatsoever and the nebula filter gives your images a very subtle, dreamlike quality. In my opinion something that is really impossible in Photoshop or with digital editing. You get the realism and quality of a real optical effect and these look absolutely gorgeous. Some people may disagree, but I always prefer to do as much as possible in camera to avoid post-processing. And for videos, this is of course a time saver. Applying this subtle fog effect digitally to video is very processor intensive. This is a neat little way to soften facial features a bit for portraits, and I decided to take a portrait of this little guy. You can really see the difference around the eyes that the filter makes, in addition to the fact that it was very bright and this filter helped soften the shadows. This is a 1/4 crap so the effect is very subtle. Don't let the Black Diffusion name confuse you. This filter brightens your images by reducing contrast and softening highlights. It actually brightens the image up a bit, but in a way that doesn't blur. That's the beauty of real optical filters and not digital post-processing effects. This compares to my German filters, which I have paid a lot more money for in the past.

This filter is of very high quality, the glass is beautifully clear, the thread is very smooth-running and the grooves on the frame make it easy to grip. The effect is clearly visible. The photos look harmoniously soft, but remain sharp. Colors are not changed. Some of the "hardness" is removed from the images without being softened. The filter is stored in a simple plastic box with foam. Nothing special, but it's well protected. The scope of delivery also includes three cleaning cloths. All in all, this is a very good product, and the price is right. Everyone has to decide for themselves whether this filter is necessary. It is always an asset and the quality is top notch. That's why we're happy to give you full stars.

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 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
