The 62mm 1.2 Natural Density Digital HT Filter is 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 Tiffens 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 thats 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.These filters reduce the amount of light passing through the camera lens without changing the color of the scene. They are especially useful in bright light conditions to help prevent overexposure. Neutral Density filters also allow proper exposure at a wider lens opening for reduced depth-of-field to highlight a key subject by making the foreground and/or background out of focus.Features: Eliminates overly bright, washed-out imagesBalances exposureControls depth-of-fieldAllows slower shutter speeds to produce blurred motion effects10 year warranty
