Protect the front of your lens with the Hoya NXT Plus 55mm UV protection filter. This is your first line-of-defense against scratches, rain, dirt and dust. With 10 layers of Hoya’s patented anti-reflection (AR) multi-coatings applied to Schott B270 filter glass, your images show improved contrast, color, and sharpness with an incredible 98% light transmission. Hoya also applies a waterproof top coat that is polished smooth for easy cleaning so dirt, smudges and water wipe away easily. The NXT Plus filter frame is 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.
