Clear Filters are completely neutral, its only task is the protection of the lens, with no change in imaging quality or speed of the lens.
The Tiffen Digital HT Filters are 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. And that's not all these High Transmission filters feature a low profile titanium finish ring and anti-reflective black lock ring, with a distinctive titanium finish that sets these filters apart from the rest.
Digital HT filters are made in the USA and come with a 10-year warranty your guarantee of quality assurance.
Digital HT filters are available as the following filters: Digital Ultra Clear, Haze 86 (with 86% UV absorption), Circular Polarizer, 812 Warming Filter, ND .06, ND 1.2, Soft/FX 3, Star 4 Point 2, and Color-Grad ND.0.6 in sizes 52mm-82mm.

This is the only filter I use on any of my lenses. When I was shooting professionally I worked around fine dirt, sand, water and animals. While others ran away from the side of a 4' pool, I would stand and get splashed, do a quick wipe and shoot some more. Now I shoot for fun, but my standards have not lowered. Every new lens gets this filter. Absolute perfection.
I use this filter on my 100mm macro f2.8 Canon lens, which is an "L" lens and I think it is great protection for an expensive lens such as this. It has worked very well for me.
