The Tiffen 94mm Coarse Thread Clear Filter is a simple, clear filter with a 1x filter factor and is designed to provide general protection for your lens. This optically clear filter does not affect the overall image quality while helping to prevent dust, scratches, moisture, and other elements from reaching or damaging your lens. This filter features standard coating for helping to reduce flare and improve light transmission.
Tiffen filters are made using ColorCore technology; a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, then mounting to precision metal rings.
