Designed to eliminate UV contamination up to 400nm, the Formatt Hitech 39mm SuperSlim UV 400 Filteris specially designed for use when photographing at high altitudes and in snow, and serves to reduce bluish casts and haze as well as increase contrast and clarity. This unique filter also features a 15-layer Firecrest coating, which further serves to minimize surface reflections and maintain light transmission for consistent color accuracy and image acuity. Additionally, a UV filter is also useful as a general protective filter to leave on lenses at all times for protection against accidental impacts or scratching to the lens.

This filter is constructed from Schott Superwite glass for maintained image quality and is set in an aluminum filter ring. The SuperSlim ring measures 5.5mm-thick and its slim design helps to minimize the likelihood of vignetting. This filter features front threads to permit stacking of additional filters or the attachment of a lens cap.
