Chrosziel 410-30 Top French Flag S16, Foldable

The Chrosziel 410-30 is a professional, foldable French flag designed for use with matte boxes that support the S16 (Super 16) format or smaller. A French flag is an essential accessory for controlling lens flare and preventing unwanted light from striking the front lens element. It consists of a rigid yet adjustable arm and a hinged, foldable flag that can be positioned precisely to block light sources such as the sun, studio lights, or practical lamps from causing veiling glare or artifacts in the image. The foldable design makes it compact for storage and transport, a key feature for location filmmaking.

Constructed with Chrosziel's signature precision and durability, the arm allows for smooth, multi-axis adjustment and locks securely in place. The flag itself is made of a lightweight, opaque material. This tool provides cinematographers and directors of photography with direct, on-set control over the quality of light entering the lens, enabling them to protect contrast and color saturation or to creatively allow controlled amounts of flare for artistic effect. It is a simple but vital component for maintaining optical integrity and achieving the desired visual style.
