About the Chrosziel 410-31 4 x 5.65" Filter Tray
The Chrosziel 410-31 is a professional-grade matte box filter tray system designed to hold up to four standard 4 x 5.65 inch (also known as 138mm) rectangular filters simultaneously. This modular component is engineered for integration with high-end cinema and broadcast camera rigs, providing cinematographers and videographers with a versatile and robust solution for managing multiple filtration layers without compromising optical alignment or causing vignetting. The tray itself is constructed from lightweight yet durable materials, typically aluminum or reinforced composite, and features a precise, low-friction sliding mechanism that allows filters to be inserted and removed smoothly and securely, even during active shooting. Its primary function is to organize and stabilize filters such as neutral density (ND), polarizers, diffusion, and color correction gels directly in front of the lens, enabling complex creative and technical control over the image.
The design of the 410-31 tray emphasizes optical precision and operational efficiency. It is built to maintain perfect parallelism between the filter stages and the lens axis, ensuring that there is no degradation in image sharpness or the introduction of unwanted reflections. The tray system often incorporates features such as adjustable tension controls to secure filters firmly, anti-reflective flocking on interior surfaces to minimize stray light, and precise markings for filter orientation. By accommodating four filters, it allows for sophisticated combinations—for example, stacking a variable ND, a polarizer, and a color grade filter to achieve exact exposure, glare reduction, and color tone simultaneously. This capability is essential for professionals working in dynamic, run-and-gun environments or controlled studio settings where lighting conditions may change rapidly.
This filter tray is a critical component within a larger Chrosziel matte box system, renowned for its modularity and build quality in the film industry. It is used by directors of photography and camera assistants to build a customized filtration setup tailored to the specific demands of each scene. The ability to quickly swap or add filters via the slide-through trays facilitates rapid adjustments on set, enhancing workflow and creative flexibility. The Chrosziel 410-31 embodies the professional standard for reliable, precise, and adaptable filter management, supporting the creation of a polished cinematic look by providing uncompromising control over light entering the camera.
