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 http://imaging.nikon.com/products/imaging/technology/scene/20/index.htm
• 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

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.

The PENTAX 645D has been developed to provide super-high-resolution images produced by large image sensors — something previously available only on professional models — to serious landscape and outdoor photographers. It combines exceptional image quality with excellent manoeuvrability and outstanding reliability to simplify professional-level outdoor shooting. Thanks to the incorporation of a large, high-performance image sensor (measuring 44mm by 33mm) and PENTAXoriginal image-processing technology, it produces extra-sharp, super-high-resolution images with approximately 40 effective megapixels. It features remarkable durability and dependability, thanks to its lightweight but solidly built body featuring a magnesium-steel-alloy frame, reinforced glass LCD panel protectors and a reliable dustproof, weather-resistant construction. In addition, it is designed to be compatible with the majority of the existing PENTAX 645 system, so that current PENTAX 645-series camera users can take advantage of their valuable assets, including high-performance SMC PENTAX 645 interchangeable lenses.
