Hoya NXT Plus UV Filter - 52mm

UV filters are most commonly used to protect the front of your lens. Hoya’s NXT Plus UV is a powerful upgrade to the best-selling NXT series. The filter applies a waterproof top coat to Schott B270 glass polished smooth for easy cleaning. 

10 layers of Hoya’s patented anti-reflection (AR) multi-coatings allow for 98% light transmission, resulting in sharp, clear images. The UV properties of the filter also allow you to reduce haze at higher elevations.

The NXT Plus filter frames are precision milled from lightweight aluminum for a slim profile that make them comfortable for all lenses, including super wide-angles. The frames have full front filter threads that can accept normal lens caps or allow you to stack additional filters like a circular polarizer or neutral density.

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. 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.
