SmallRig 4412 Overview

Add polarizer and VND filtering assembly directly onto your lens with this Filter Kit with Adjustable Clamp from SmallRig. The kit includes an adjustable 67-82mm lens clamp, two circular polarizer filters, a Black Diffusion 1/4 filter, a lens cap, and a dust cover. The filters are magnetic and can be stacked in the lens clamp, and the two magnetic circular polarizer filters can be used together to create a VND effect.

The CPL filters can be adjusted for 2 to 5 stops of light reduction into the lens. The Black Mist 1/4 filter creates a dreamy and romantic atmosphere by softening highlight detail, softening skin, and lowering the contrast and sharpness, all while preserving shadow detail. There is no vignetting for lenses with a focal length of ≥16mm. The filters are made from optical glass that features multicoating for accurate color rendition within 350 to 700nm wavelengths.

Quick Features
  • 67-82mm adjustable clamp design with a three-point locking system
  • Kit includes CPL, VND, and Black Diffusion 1/4 filters for versatile functionality.
  • Quick release magnetic system ensures safe and efficient filter changes
  • Hard stops and light transmission limit technologies eliminate the VND X-pattern effect

  • Dual-sided 16-layer coating provides a smooth, film-like texture and consistent color rendition
  • Includes a dustproof cap and lens cover  
  • Vignette-free performance across focal lengths ≥16m

Does this work with the mini matte box lite?

Does this work with the mini matte box lite?
Asked by: Patrick
The SmallRig Filter Kit with Adjustable Clamp is not designed to work with a matte box. It attaches directly to a lens.
