Hoya - 62MM NXT Plus UV Filter

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.
