Hoya 77mm NXT Plus UV HMC Multi-Coated Slim Frame Glass Filter

The Hoya NXT Plus UV Filter is a multi-purpose filter that is most commonly used to protect the front of your lens,

a first line of defense against scratches, rain, dirt and dust. Hoya's

NXT Plus UV is a powerful upgrade to the best-selling NXT series. This

filter applies a waterproof top coat to Schott B270 glass

polished smooth for maximum sharpness. There are two advantages to

having a premium waterproof coating: (1) Water beads-up quickly, and

easily slides off the surface of the filter for streak-free shooting.

(2) It also makes the filter a lot easier to clean when dirt, water, and

smudges make their way onto the surface. Hoya applies 10 layers of patented anti-reflection (AR) HMC multi-coatings to the NXT Plus UV filter for improved contrast, color, and sharpness. The coatings deliver a 98% light transmission

so you don't have to worry about contrast-killing glare. The NXT Plus

filter frames are precision milled from lightweight aluminum for a slim profile that makes it perfect for all lenses including super wide-angles. What else does a UV filter do? Most photographers leave a UV filter attached to the lens all the time as a form of protection. But the filter also plays an important role in filtering through UV Haze.

Haze is not a huge problem when you are taking pictures at sea-level,

but as you hike into higher altitudes, the filter definitely helps cut

through the haze to increase contrast and improve color. The NXT plus has a UV Cut Point of 360nm or L36 which is superior to most filters at this price point.
