An ultra-wide field of view along with a sleek form factor, the NIKKOR Z 20mm f/1.8 S from Nikon is a versatile prime well-suited to a range of subject types, from architecture to interiors to landscapes. An advanced optical design uses aspherical and ED elements to produce sharp, well-corrected imagery with high clarity and color accuracy, and both Nano Crystal and Super Integrated Coatings are also used to suppress flare and ghosting for greater color fidelity and higher contrast.
Complementing the optical design, a multi-focus system, which employs two stepping motors, helps to realize impressively fast, accurate, and quiet focus performance, along with full-time manual focus override, to suit both stills and video needs. Additionally, a programmable control ring can be set for intuitive adjustment over a variety of camera and exposure settings.
The Hoya 77mm 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 helps it to stay clean for longer than 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.
