The Hitech filter system is a versatile system designed for use by professional photographers working with large, medium or small formats. This holder is available for special situations. It has one filter slot for 100mm wide x 1.5mm thick filters and the 105mm threaded front ring. This is useful when you need to use a polarizer with a wide-angle lens.
The standard Hitech filter holder (B&H Catalog# HIFH44) will accommodate up to three slide-in filters 100mm wide x 1.5mm thick. A large 105mm threaded mounting ring on the front of the holder accepts high-quality glass screw-in filters and lens hoods.
A wide-angle holder (B&H Catalog# HIFHWA44) is available for use with extra wide-angle lenses or for when extensive movements are applied to large format cameras. This version offers two slots for 100mm wide x 1.5mm thick filters and has no front ring.
Adapter rings are available from 49-105mm, Bayonet sizes, adapters for mounting the holders on the rear elements of view camera lenses, and special wide-angle adapters.
