Tiffen 55mm Digital HT ND 1.2

This filter absorbs 4 stops of aperture, ensuring balanced exposure and better depth of field control. High transs titanium filters have very high transmission properties with multi-coatings and a titanium oxide component. These filters are mounted in a lightweight metal ring with a matte black anti-reflective inner ring and a titanium finnish outer ring to identify the titanium oxide component in the filter. The new coatings for this filter increase hardness and reduce smearability. Manufacturer's Description The ND 1.2 has a light transmission of 6.25% or a Filter Factor of 16x. Neutral Density filters evenly reduce the amount of light passing thru the lens without effecting color. Ideal for reducing bright light in large aperture situations when a narrow depth of field is needed. Allows for slower shutter speeds when blurring or showing of movement is desired. Allows balancing of exposure to highlight a key subject. Lets you use higher speed films in bright light. 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. Tiffen Digital HT Filters Made from the purest optical quality glass and Tiffen's award-winning ColorCore technology, Tiffen Digital HT - High Transmission - filters offer a new breakthrough in multi-coating technology. Imagine, a double-sided coated filter with the strength of titanium, unmatched scratch-resistant durability and worry-free cleaning. Other coated filters on the market today cautiously suggest delicate, if any, cleaning procedures, in fear of destroying the coating (and thereby the filter). Not with the Digital HT filters - the secret is in the titanium coating that makes it extremely durable and protects against damage and mark up.
