Baader UFC Filter Slider [50 - 50.5mm Unmounted]

This is one of the interchangeable filter sliders for Baader's UFC system, and in this case is designed to hold 50 - 50.5mm Unmounted filters. UFC is an acronym for Universal Filter Changer, and the UFC system is exactly that; a highly modular system of interchangeable parts that come together to create a system that can be used to freely exchange filters with minimal effort during imaging sessions.
