Hoya 52mm 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.
