Thin Rim, Multicoated - ideal for wide-angle and high quality lenses.
Digital HT Filters
Digital HT filters are a state-of-the-art technological breakthrough in multi-coated photo and video filters. Made for the discerning professional and imaging enthusiast, Digital HT filters with Hi-Trans? Double-Sided Titanium Multi-Coating surpass even military specifications for hardness and durability.*
Digital HT - High Transmission - filters offer the strength of a Titanium coating combined with the purest optical quality glass and Tiffen?s Academy-Award-winning ColorCore? 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 these filters apart from the rest.
Digital HT Color-Grad Neutral Density Filters
Often, you want to balance light intensity between two areas within a scene. This is important outdoors to allow more sky detail while properly exposing the foreground. Exposing for the foreground will produce a washed-out, over-exposed sky, exposing for the sky will leave the foreground dark, underexposed.
