The Fujinon XA20SX8.5BRM-K3 is a 20x ENG telephoto lens for 2/3" format cameras, covering the same 8.5-170mm focal range as the BERM-configuration version, with relative aperture running 1:1.8 across 8.5-113mm and easing to 1:2.7 at the 170mm long end. Inner Focus technology and advanced glass properties reduce the colour fringing that comes from a lens failing to focus every colour to the same convergence point, and Fujinon's EBC optical coating supports high-quality optical transmission through the zoom range. Servo zoom and focus are fast, quiet and precise, and the lens carries an ergonomic handgrip for handheld operation. Fujinon positions it for video production in settings such as weddings, houses of worship and corporate offices, alongside broadcast ENG use.
