The AF-S Nikkor 400 mm f/2.8E FL ED VR lens and AF-S Teleconverter TC-14E III are aimed at professional and what Nikon terms “passionate” photographers. The 400 mm lens is lighter and more durable than its predecessor, and the teleconverter is said to boost the focal length while maintaining detail and sharpness.
The 400 mm lens delivers enhancements to the optical characteristics of the lens, a refined optical formula, as well as improved autofocus (AF), exposure accuracy and speed. The lens now contains two fluorite elements that, together with two Extra-Low Dispersion (ED) glass elements and Nano Crystal Coat, help ensure what the company is terming outstanding performance with minimal chromatic aberration and flaring.
The internal construction of the lens comprises 16 elements in 12 groups, and features an electromagnetic diaphragm, similar to that employed in the AF-S Nikkor 800 mm f/5.6 lens. Denoted by the “E” designation, this feature allows for stable exposures during high-speed shooting, such as the ability to shoot at 11 frames-per-second (fps) with the Nikon D4S.
Additionally, the lens employs a nine-blade rounded diaphragm that creates a circular, natural-looking out-of-focus area.
The refined construction of this lens has additional benefits, creating a “beautifully balanced instrument” for professionals that is nearly two full pounds (816 grams) lighter than its predecessor.
Nikon’s Vibration Reduction (VR) technology delivers up to four stops of image stabilization.
New VR Sport Mode, when shooting action, especially on a monopod, recognizes a panning motion to provide accurate compensation for camera shake, resulting in super-sharp images, with motion blur where the photographer intended.
For working in challenging environments, the lens features a protective front meniscus element with a fluorine coating which resists dirt and moisture on the front of the lens. Other pro-minded features include the addition of a rotating tripod collar for seamless switching between compositions, and buttons on the lens barrel compatible with the new AF functions of the Nikon D4S.
The new 1.4x teleconverter is said to retains the lens’ image quality, even at wide-open apertures, and the enhanced optical system reduces chromatic lens aberration, while preserving the accuracy of the AF system.
The construction of the teleconverter has been significantly upgraded for both durability and optical brilliance. Comprising seven elements within four groups, the outer elements feature a fluorine coating for enhanced resistance to dirt and water droplets. For added durability, the lens barrel has been designed for increased moisture and dust resistance.
The AF-S Nikkor 400 mm f/2.8E FL ED VR lens is scheduled to be available late August at a manufacturer’s suggested retail price (MSRP) of $13,199.95.
The AF-S Teleconverter TC-14E III is scheduled to be available in late August at an MSRP of $549.95.
