K&F CONCEPT Black Diffusion Filter 1/4 52 mm and 3 Vacuum Packed Cleaning Cloths Black-Mist Cinematic Effect Filter for Digital Camera Lens (K-Series)

Perfectoo

Did not show the misty effect as much as i expected.. but its nice

I've always been on the lookout for tools and accessories that can elevate my videography to the next level. And this is one of the best! By the way, the seller is very efficient and polite :-)

I bought the 1/8 filter first and it's ideal for a subtle glow and at night. This 1/4 is perfect for daytime when you need a bit more strength for a more pronounced glow effect. These filters feel high quality and come in a nice box. My only suggestion for improvement is to label the boxes what's in them. They are semitransparent and you cannot tell what's in them.

رااااايق الضباب فيه جدا خفيف وللاضاءه القويه يسوي لها بلور

J’utilise le K&F Concept Black Diffusion 1/4 régulièrement sur mes objectifs Tamron 28-75mm f/2.8 et Sony 70-350mm f/4.5-6.3 ayant un diamètre de 67mm avec mon Sony a6700, pour la photo et la vidéo. Après plusieurs mois, je suis très satisfait du rendu qu’il apporte à mes images. Points forts : • Rendu cinématique : adoucit les hautes lumières tout en conservant un style naturel et professionnel. • Diffusion 1/4 équilibrée : ni trop marquée (comme un 1/2), ni trop discrète (comme un 1/8), idéale pour un usage polyvalent. • Simple à utiliser : il suffit de visser le filtre sur l’objectif. • Compatible avec d’autres filtres : pratique pour le combiner avec un filtre ND ou tout autre filtre du même diamètre. • Bonne qualité de fabrication : solide, fiable pour un usage régulier sur le terrain. Point à améliorer • Grip parfois difficile : il m’arrive de ne pas réussir à le dévisser lorsqu’il est combiné avec un autre filtre. Dans ce cas, il faut soit le manipuler hors de l’appareil, soit garder les deux filtres vissés ensemble, ce qui peut être contraignant selon la situation. Il existe en revanche des solution pour le défaire avec un tissu ou un élastique. En résumé je dirais que c’est un excellent filtre pour celles et ceux qui cherchent à donner un aspect cinématique à leurs images. Le 1/4 est parfaitement dosé pour un rendu naturel et polyvalent, et malgré un petit défaut de maniabilité, c’est un outil efficace et agréable à utiliser, surtout en combo avec d’autres filtres.

Este filtro da un efecto increíble, me encanta la calidad

I grabbed the K&F Concept Nano-X Black Mist 1/4 Filter (82mm) from Amazon a few days ago to pair with my Canon EOS R5 and 7artisans 35mm T1.05 lens, and holy cow, this little piece of glass is a game-changer for my YouTube videos and photos! As a content creator chasing that dreamy, film-like vibe, I’ve been testing this filter for both video and stills, and here’s my honest take.What’s Awesome: Cinematic Glow: This filter adds a subtle, hazy glow to highlights that screams “Hollywood” without overdoing it. Shooting with my R5 and 7artisans lens at T1.05, I got gorgeous, bloomy highlights in backlit scenes—like streetlights at dusk or window light on a subject—that make my vlogs look straight out of a movie. The 1/4 strength is perfect; it’s noticeable but not so heavy that it screams “filter!” Softens Without Sacrificing Detail: The filter softens harsh edges and reduces contrast, giving my footage and photos a less “digital” feel. Skin tones look smoother (great for talking-head videos), yet I still get sharp details in the focus area. Paired with the 7artisans lens in crop mode on my R5, it’s a dreamy combo for portraits and product shots. Top-Notch Build: The aviation-grade aluminum frame feels solid, and the 28-layer nano-coating is legit—scratch-resistant, waterproof, and no glare issues in my tests. It screws smoothly onto my 7artisans lens, and at just 26g, it doesn’t add bulk to my SmallRig cage setup. The included hard plastic case is a nice touch for keeping it safe in my bag. No Vignetting Worries: I was stoked to find zero vignetting, even with the 35mm lens in APS-C crop mode (about 56mm equivalent). This matches what I’ve read online—no edge darkening, even in bright daylight or wide-open apertures. Budget-Friendly: At around $40-$60 for the 82mm size, this filter is a steal compared to pricier brands like Tiffen or Moment. It delivers pro-level effects without draining my wallet, which is huge for an indie creator like me. What’s Not Perfect: Subtle in Some Scenes: In flat or low-contrast lighting, the effect can be so subtle you barely notice it. I shot some overcast outdoor scenes, and the mist effect was less pronounced than I hoped. It shines most with strong highlights (e.g., neon signs or backlighting), so plan your shots accordingly. Slight Warmth: I noticed a tiny warming effect on colors, especially in daylight. It’s not a dealbreaker (easy to tweak in post with Premiere or Lightroom), but it’s worth noting if you’re obsessive about color accuracy. Not for Every Shot: This isn’t a filter you’ll leave on all the time. For crisp, high-contrast landscapes or super-detailed product shots, I take it off to avoid softening the image too much. It’s more of a creative tool than a must-have like an ND filter. Learning Curve for Video: For video (like my YouTube b-roll), the effect looks best at wider apertures (T1.05-T2.8). At smaller apertures (e.g., T5.6), the diffusion can feel underwhelming. It took a few test shots to dial in the right look with my Zhiyun Crane 2 setup. The Verdict: The K&F Concept Black Mist 1/4 Filter is a must-have for creators who want to add a cinematic, film-like vibe to their videos and photos without spending a fortune. It’s transformed my R5 footage with the 7artisans 35mm lens, giving my vlogs and portraits a soft, glowing aesthetic that’s perfect for storytelling. The build is solid, it plays nice with my gear, and the price is unbeatable for the quality. Just know it’s a specialty tool—best for scenes with strong highlights or when you want that dreamy, nostalgic feel. I’m already eyeing night shots with neon lights to see how it pops! If you’re an indie filmmaker or photographer looking to level up your visuals, this filter’s a no-brainer. Grab it, play with it, and watch your shots turn magical!
