The AC-411-50 4x4 Clamp-on SunShade by Chrosziel is a mattebox/filter holder that is made for internal focus broadcast lenses. This unit will work with 4:3 aspect ratios and also comes with a 16:9 mask. Made for focal lengths that widen to 5.2mm, it will also work with wider lenses by way of a special stepdown ring, which allows focal lengths down to 4.5mm. This unit as a whole works as a mattebox, enabling the user to add more control to the image--perfect for videographers shooting film-style and event shooters wanting to upgrade their image quality.
