We'll made, value for money. Protective case it comes in is also great value for money and looks great. Review: Great diffusion filter - The first thing that caught my attention was the slim and compact design of the filter. It easily fits into my matte box without adding any extra weight or bulkiness. The 4mm thickness is perfect for minimal light loss, and the HD optical glass ensures crystal clear images. The multi-layer coating also helps to reduce reflections and maintain color accuracy. One of the standout features of this filter is its compatibility with various matte boxes, including Tilta and SmallRig. It's a great option for those who use different equipment and don't want to invest in multiple filters. The build quality is also impressive, and I can tell that it's built to last. But the real game-changer for me was the diffusion effect. This filter creates a beautiful softening effect while still maintaining the sharpness of the image. It's perfect for portraits and adds a dreamy quality to the photos. I found myself using it more often than I initially thought I would. ## Features - 4"x5.65" Square Filter for Matte Box: The 4-inch black diffusion filter is compatible with Tilta's SmallRig Matte Box and Mini Matte Box. Simply place the filter on the matte box and place the whole set in front of the camera lens to create a hazy, cinematic look for professional photography and videography. - 1/8 Black Diffusion Filter for Cinematic Effect: The 1/8 black mist filter effectively reduces highlights and reduces glare to provide smoother and softer skin tones for a dreamy cinematic effect on video and photo images. Ideal for portrait photography, video recording and vlogging. - Clearer, higher contrast images: With 0.2% reflectivity control, our Matte Box ND filter prevents lens ghosting and halo effects, delivering clearer, higher contrast images with richer detail. Perfect for 4K/8K HD video recording. - Scratch Resistant and Water Repellent: Made from high quality HD optical glass, our filter features a 28-layer nano-coating on both sides to reduce reflections and glare. It's also oil-resistant, water-repellent and scratch-resistant for long-lasting use. - Leather Pouch for Added Protection: Apart from a 1/8 black mist filter, our package includes a leather filter pouch lined with thin sponges to protect your filter from damage during storage and transportation. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CQJYDS8F | | Best Sellers Rank | 84 in Photography Effect Filters | | Brand | K&F CONCEPT | | Brand Name | K&F CONCEPT | | Coating Description | 28-layer coatings | | Coating description | 28-layer coatings | | Colour | black | | Compatible Devices | Tilta, SmallRig | | Country of Origin | China | | Customer Reviews | 4.8 out of 5 stars 45 Reviews | | Enclosure Material | Optical Glass | | Item Dimensions L x W | 14.4L x 10.2W centimetres | | Item Weight | 334 Grams | | Manufacturer | Shenzhen Zhuoer Photograph | | Manufacturer Part Number | KF01.2452 | | Material | Optical Glass | | Media Type | ProductImage | | Number of Items | 1 | | Number of Packs | 1 | | Photo Filter Effect Type | Black Mist | | Photo Filter Factor | 8 x | | Photo Filter Size | 4 Millimeters | | Photo Filter Thread Size | 4 Millimetres | | Photo filter effect type | Black Mist | | Photo filter thread size | 4 Millimetres | | Screen Size | 5.65 Inches | | Set Name | Nano-X | | Unit Count | 1.0 count | | Water Resistance Level | Waterproof | | Water resistance level | Waterproof | ## Product Details - **Brand:** K&F CONCEPT - **Coating Description:** Multi Coating - **Material:** Optical Glass - **Photo Filter Effect Type:** Enhancing - **Photo Filter Factor:** 2 x - **Photo Filter Thread Size:** 4 Millimeters - **Product Dimensions:** 4"L x 5.65"W - **Set Name:** Nano-X - **Unit Count:** 1.0 Count - **Water Resistance Level:** Waterproof ## Images ![K&F CONCEPT Square Black Diffusion 1/8 Mist Filter 4"x5.65" Optical Glass - Image 1](https://m.media-amazon.com/images/I/71sxbsiQmVL.jpg) ![K&F CONCEPT Square Black Diffusion 1/8 Mist Filter 4"x5.65" Optical Glass - Image 2](https://m.media-amazon.com/images/I/71nbJPG1NZL.jpg) ![K&F CONCEPT Square Black Diffusion 1/8 Mist Filter 4"x5.65" Optical Glass - Image 3](https://m.media-amazon.com/images/I/61ZCZv5ZzfL.jpg) ![K&F CONCEPT Square Black Diffusion 1/8 Mist Filter 4"x5.65" Optical Glass - Image 4](https://m.media-amazon.com/images/I/51J4PDuWAVL.jpg) ![K&F CONCEPT Square Black Diffusion 1/8 Mist Filter 4"x5.65" Optical Glass - Image 5](https://m.media-amazon.com/images/I/716uNJTpRML.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product. *by A***R on 31 December 2024* Produces a great effect.
