【Multi-Layer Nano Coatings】The double-sided 30 layers of nano coatings are waterproof & scratch resistant, and oil-proof, effectively reducing the reflection came from the filter itself and the ground.
【CNC Non-Slip & Ultra Slim Frame】This black diffusion 1/4 filter ultra-slim frame with CNC trapezoidal pattern frame features only 0.13in/3.3 mm on thickness and avoids vignetting and dark corners on wide-angle and telephoto lenses; CNC non-slip design frame is easy to install and remove.

Pros & Cons
👍 Pros
- Effectively reduces highlights and glare, creating a smoother skin tone and a dreamier, softer aesthetic in images and videos.
- Made from Japanese AGC HD optical glass with 89% light transmission, ensuring high-definition quality without significant light loss.
- Features 30 layers of double-sided nano coatings, making it waterproof, scratch-resistant, and oil-proof for enhanced durability.
- The ultra-slim 0.13in/3.3mm CNC trapezoidal pattern frame prevents vignetting on wide-angle and telephoto lenses.
- Its CNC non-slip design frame allows for easy installation and removal from compatible 40.5mm lenses.
👎 Cons
- The 1/4 diffusion strength may not be sufficient for users desiring a more pronounced or intense hazy film effect.
- Requires verifying the camera's lens thread size, as it is only compatible with 40.5mm lenses, limiting universal application.
- While reducing glare, it slightly decreases light transmission to 89%, which could be a minor factor in very low-light conditions.
- The filter's specific softening effect, while desirable for portraits, might not be suitable for all types of photography where maximum sharpness is crucial.
- Its primary use case for portrait photography, video recording, and vlogs means it might be less versatile for other photographic genres.
