UV
filters are 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. The new
filter applies a waterproof top coat to Schott B270 glass polished
smooth for easy cleaning. Dirt, smudges and water wipe away easily.
Using 10 layers of Hoya’s patented anti-reflection (AR) multi-coatings
your images show improved contrast, color, and sharpness with a 98%
light transmission. So, leaving it on all the time will not hurt your
images.
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. The frame sports full front filter threads
that can accept a normal lens cap or allows 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.
