AF-S NIKKOR 85mm f/1.4G - sample shots

Nikon launches new cream machine!

19 August 2010:

Nikon has announced the launch of its much anticipated new 85mm F/1.4 lens ...the AF-S Nikkor 85mm f/1.4G.

This lens supersedes the highly acclaimed AF Nikkor 85mm f/1.4D IF known affectionately among Nikon users as the ‘cream machine’. The latest reincarnation of this legendary lens has a totally new optical design, Silent Wave Motor (SWM) ...and Nano Crystal Coat. UK RRP: £1499.99

AF-S NIKKOR 85mm f/1.4G Main Features:

• Fast, high-performance mid-telephoto 85mm fixed focal length lens with a maximum aperture of f/1.4
• New optical design that makes the most of the performance expected of the latest fast fixed focal length NIKKOR lens
• Nano Crystal Coat adopted to significantly reduce ghost and flare. Please click on the following link for more information concerning NCC
• Equipped with a Silent Wave Motor (SWM) for extremely quiet autofocusing
• Equipped with two focus modes, M/A and M, featuring a new and improved manual focus drive mechanism that reduces manual focus time lag for improved manual focus operation in M/A mode.
• Nikon's internal focusing (IF) system has been adopted with no increase in the length of the lens

Brief Glossary:

The G-type NIKKOR has no aperture ring; aperture should be selected from camera body.

Nano Crystal Coat
Nano Crystal Coat is an anti-reflective coating that originated in the development of NSR-series (Nikon Step and Repeat) semiconductor manufacturing devices. It virtually eliminates internal lens element reflections across a wide range of wavelengths, and is particularly effective in reducing ghost and flare peculiar to ultra-wideangle lenses. Nano Crystal Coat employs multiple layers of Nikon’s outstanding extra-low refractive index coating, which features ultra-fine crystallized particles of nano size (one nanometer equals one millionth of a mm). Nikon now proudly marks a world first by applying this coating technology to a wide range of lenses for use in consumer optical products.

Silent Wave Motor
Nikon's AF-S technology is yet another reason professional photographers like NIKKOR telephoto lenses. AF-S NIKKOR lenses feature Nikon’s SWM which converts “traveling waves” into rotational energy to focus the optics. This enables high-speed autofocusing that’s extremely accurate and super quiet.

Internal Focusing (IF)
Imagine being able to focus a lens without it changing in size. Nikon's IF technology enables just that. All internal optical movement is limited to the interior of the nonextending lens barrel. This allows for a more compact, lightweight construction as well as a closer focusing distance. In addition, a smaller and lighter focusing lens group is employed to ensure faster focusing. The IF system is featured in most NIKKOR telephoto and selected NIKKOR zoom lenses.
