AF-S NIKKOR 400mm f/2.8E FL ED VR

Overview

Employs two fluorite and two ED glass elements plus Nano Crystal Coat to achieve high optical performance with minimized chromatic aberration.
Weight of approx. 3,800 g is realized through the employment of fluorites and increased use of magnesium alloy for the lens barrel.
The adoption of an electromagnetic diaphragm mechanism contributes to stable exposure control even during high-speed continuous shooting.
Tripod mount ring employing bearings ensures smooth switching between horizontal and vertical orientation while providing improved durability.
Vibration Reduction (VR) function provides an effect equivalent to a shutter speed 4.0 stops faster* (in NORMAL mode).
- *Based on CIPA Standard. This value is achieved when attached to an FX-format digital SLR camera.
"SPORT" mode, newly adopted as a VR mode option, is specially effective when shooting sports, for example, in which subjects are radically moving.
Fluorine coat applied to a meniscus protective glass at the lens front repels dirt or water droplets, ensuring easy removal.
