Digital HT^TM - High Transmission - filters offer the strength of a Titanium coating combined with the purest optical quality glass and Tiffen's Academy-Award-winning ColorCore^TM technology.  They present unmatched scratch-resistant durability and worry-free cleaning while other coated filters on the market today cautiously suggest delicate, if any, cleaning procedures, in fear of destroying the coating (and thereby the filter).
 
And that's not all - these High Transmission filters feature a low profile titanium finish ring and anti-reflective black lock ring which sets them apart from the rest.
Digital HT^TM filters are made in the USA and come with a 10-year warranty - your guarantee of quality assurance.  Each filter comes with its own distinctive soft pouch for storage when not in use.
 
Along with the extreme toughness and durability, Tiffen Digital HT^TM Titanium Coating features excellent Anti-Reflective and Transmission (HT - High Transmission) characteristics. The Titanium coating consistently reflects less than 1% of the imaging light hitting the front surface of the filter while transmitting nearly 99%.
