Hoya - 62MM NXT Plus UV Filter

The Hoya 62mm NXT Plus UV Filter is a general-use, clear filter designed to absorb ultraviolet light and reduce the bluish cast of daylight. Aside from the reduction of unwanted blue casts, no additional coloration or contrast is created, and adjustments to exposure are not required while using this filter. To prevent internal ghosting and reflections, each glass surface includes five layers of anti-reflection coating. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer with uncoated filters. An additional hydrophobic coating results in an improved beading effect when in contact with water for greater cleaning efficiency. This NXT Plus UV filter is constructed from Schott B270 glass for increased clarity as well as color fidelity and features an aluminum-alloy filter ring for durability while remaining lightweight. It is also useful as a general protective filter to leave on lenses at all times. Such filters help to reduce dust and moisture from reaching your front lens element and provide additional protection in case of drops or situations where scratching could occur.

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.
