This is a great quality filter, it latches on nice and tight, and adds a subtle bloom (I bought the 1/8) to my photos. It's sturdy and surprisingly thin, I never take it off. It's a subtle effect but still noticeable! The generous microfiber cloths add to the value, with everything being extremely well packaged. I will be buying more of these filters for my other lenses.

Softens highlights and increases bloom. Quite happy with it.

I reviewed this product in February and March of 2023.

Well packaged and came with cleaning cloths that came in handy. This filter adds just a little bloom to the image as shown in the pictures I added of my old Nikon F in low light. You can see the one with the filter has slightly more bloom and cine softness than the other. This is subtle and doesn't take the image too far in my opinion.

I used this on a few portrait sessions and while I normally like to keep the sharpness dialed up this does really well when you have a subject that can benefit from a little softer skin.

I enjoyed using it and I'll be adding it to my kit.

The 82mm Black Mist 1/8 filter gives a nice soft, cinematic glow to highlights without losing too much sharpness. It reduces digital harshness and adds a subtle dreamy atmosphere to both photos and videos. Build quality feels solid, and it fits my lens perfectly. A great tool if you want to achieve a more film-like look.

I have tried, and own, different grades of black diffusion filter. I think for its subtle effect, this 1/8 filter is my favorite. The smooth look, and highlight diffusion that you get with these filters, is either an acquired taste, or a specific characteristic that you're looking for in your shots. I personally don't use them all the time, but it is nice to bloom the highlights in certain scenarios. The 1/8 filter is very subtle in the daylight, but I found excels at night. You can of course, use it with decent effect during the usual golden hours, as the intensity of the highlights then, may be more visibly changed by this filter, photographically. In the daytime, with the sun right above you, it's hard to notice much of a difference. For video, it does an interesting effect, and may be something that you can apply to specific scenes, or just to unsharpened some of the digitized look from most cameras. Quality of the filter is very nice, made of good materials, and with nice coatings. It comes well packaged, in your standard plastic case, as well as included sealed microfibre cloths. It is affordably priced, and performs very nicely, for that price range. It doesn't in any way appear cheap to me, and like mentioned before, I do like the subtlety of this gradient. It's certainly good for the camera bag, and would be interesting to try with some golden hour portraiture. For video, I'd say it's limited to dreamlike sequences, and better suited for golden hour, and night time. All in all, I'm very pleased, and if you're looking for a 1/8 black diffusion filter, this one is a good choice.

For the price, this thing is incredible.Quality is totally fine for the price. The effect is most extreme when the dynamic range is greater, such as bright lights or backlit scenes. It's subtle enough to leave it on my lens and not even think about it. Image quality is great.

1/8 is the perfect diffusion. takes the edge off without getting all 'ethereal' or unrealistic looking. seems to help with Sony on making the digital feel less pronounced. only weird artifacting you get is at the super wide end, closer to 16mm (full frame) so i don't use it on my 16-35.

Awesome fit, clean. Have them for all my lenses!

Excellent Filter for Softening Light

A solid choice for photographers and videographers looking to enhance their shots with a smooth, professional feel.

I recently started using this mist filter with my Canon RF 24-70mm lens for video work, and I’m loving the effect it gives. If you’re looking to add that cinematic, dreamy feel to your footage, this filter is a must-have.

Cinematic Look: The biggest thing I’ve noticed is how it creates a subtle glow around highlights, giving my footage that soft, filmic vibe. It smooths out harsh lighting and makes everything look a little more polished and dreamy —perfect for a night time environment with lights.

Perfect for Lighting: If you're working with natural or low light, this filter helps create a gentle diffusion effect without washing out the image. It makes lights look more natural, especially street lights or practical lights in the background, giving them a soft, glowy effect that looks stunning on camera.

Build Quality: The filter is solid, feels durable, and fits snugly on my Canon RF lens with no issues. No noticeable vignetting, and I haven’t had any problems with color shifts. It's easy to screw on and off, and the glass quality is top-notch.

Easy to Use: It’s super simple to use for video—you just pop it on and start shooting. I’ve used it in both daylight and night scenes, and it always enhances the image without requiring major changes to my settings or lighting setup. Just a perfect addition if you want to add that extra flair to your footage.

Overall: If you’re into video production and want to up your game with a little more atmosphere and softness, this mist filter is definitely worth it. It adds that cinematic touch that makes your shots look more professional and polished, especially for portrait shots or any scene where you want that dreamy, moody aesthetic.
