Tiffen Digital HT 0308-30M BDHTFILT User manual

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.*
Tiffen’s research and development team has
conquered the challenges of multi-coating. No
longer is your investment in a multi-coated filter
subject to the everyday challenges of dirt, humidity,
and potential scratching which can render
your multi-coated filter useless.
Tiffen Digital HT™
A Major Breakthrough
in Multi-Coated Filters
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 that set them apart from
all other filters.
