The Aputure F10 Fresnel is a 250mm diameter Fresnel lens made of real glass, tailor-made to fit traditional 10 inch Fresnel lights (tungsten 5K or 2500W HMI etc). This Fresnel is ideal for filmmakers who require a hard-light that maintains a subtle soft quality for enhanced dramatic expression. It uses Aputure's dual-lens optical design to further enhance output, allowing a smooth focusing of light (tight 15° to a 45° medium flood). When used with the compatible Aputure LS 600d, this Fresnel lens modifier can output over 200,000lux at 1 meter. Further to this, the Aputure F10 has the same adjustable focus design from the Fresnel 2X, focusing on precise and ergonomic adjustments on set. Another key feature is its built-in ventilation system to prevent overheating - also helping to minimise light leak. The F10 is compatible with the Aputure F10 Barndoors, a winning combination for professional gaffers and cinematographers.
