Advanced Apochromat Optical System with ED (extra-low dispersion) glass minimises chromatic aberration to the furthest limit of the visible light range, realising a contrast-rich, clearer field of view
Field Flattener Lens System provides consistent sharpness across the entire field of view, all the way to the periphery
Multilayer coating is applied to all lens and prism surfaces for natural and bright images
Bright and clear view is achieved with a total reflection prism.
Straight models use a Porro prism, while angled-type models employ Nikon's original prism.
Optimised Focusing System provides different focus speeds that allow you to operate at an optimised speed; fine action for focusing on distant subjects and coarser action for nearby subjects
