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. It presents unmatched scratch-resistant durability and worry-free cleaning. 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. Along with the extreme toughness and durability, Tiffen Digital HT Titanium Coating features excellent Anti-Reflective characteristics. The Titanium coating consistently reflects less than 1% of the imaging light hitting the front surface of the filter while transmitting nearly 99%.

This filter arrived in used condition. It had adhesive on both sides of the glass surface as well as accumulated dirt around the edges of the glass perimeter. It took over an hour to clean with lens tissue. I take much pride in my optics and am disappointed in Amazon for this situation.

How can one review a filter like this one? It's just a very plain, simple filter... that will not produce flare or make light bounce within the front element and the back of the filter. That alone merits mention: buy this filter for your lenses with a 77mm diameter front because it will do what it's supposed to do.

Does just what it's supposed to do, protect the front lens of my RATHER EXPENSIVE ( but marvelous ) Canon ef 70-200mm f2.8L IS lens.
I always put a UV filter on a new lens right out of the box and LEAVE IT ALONE. Cheapest lens insurance you can buy.

It is not the best UV filter you can buy, but definitely good value for the money.

I have it mounted on my tokina 11-16/2.8 to protect my investment.

So far I removed it only once when it was causing a flare that I did not want in the picture.

Definitely a must have.

For 70$ or so you get three 77mm NEW Name Brand Lenses.

Great buy for the money. They shoot clear pics.
