Nikon announces 10-24mm F3.5-4.5G ED lens

Nikon launches the AF-S DX NIKKOR 10-24MM F/3.5-4.5G ED


New ultra-wide-angle zoom with SWM

Amsterdam, the Netherlands, 14th April 2009 Nikon Europe is pleased to announce the introduction of the AF-S DX NIKKOR 10-24MM F/3.5-4.5G ED lens. This new NIKKOR DX-format ultra-wide-angle zoom lens has a focal range starting at 15mm equivalent in FX/35mm format.

At a very affordable price, this new lens with superior build quality would be a great addition to anyone’s Nikon system. It is perfect for users wanting to shoot scenes that require a wide angle perspective effect such as in a small room, or for shooting architecture and landscapes.

Ludovic Drean, Product Manager Lenses at Nikon Europe B.V says: “This great new lens is perfectly suited for Nikon D300 and D90 users, and works very well with our other mid-class DSLRs too. Thanks to its Silent Wave Motor, it is also suitable for models without a built-in motor such as the D40 and the D60, for example. Its affordable price is no reflection on its superior quality, though, as its high-reproduction performance, minimum distortion and build quality are almost equivalent to those of the AF-S DX Zoom-Nikkor 12-24mm f/4G IF-ED.”

Superior quality build and excellent reproduction capacity
The AF-S DX NIKKOR 10-24MM F/3.5-4.5G ED offers a focal length between 10 to 24mm and a picture angle equivalent to a focal length of 15 to 36 mm in FX/35mm format. Thanks to its ring-type Silent Wave Motor (SWM), its autofocus is quiet and fast. Housed in a compact and lightweight body with Nikon’s unique high-quality exterior design, the NIKKOR advanced build quality ensures smooth operation and durability.

The optical system features ED glass and a-spherical lenses optimised for digital SLRs with an excellent capacity for accurate image reproduction, delivering high-resolution, high-contrast images whilst minimising chromatic aberration. Using the internal focusing (IF) system, the lens barrel length does not change whilst focusing, giving it a more durable build and allowing for the use of heavy attachments.

The lens also has two focus modes – M (Manual) and Manual-priority auto (M/A). M/A mode enables a user to switch rapidly between autofocus and manual focus by merely rotating the focus ring even during AF operation. This allows precise focus adjustment without taking your eye off of the viewfinder.

The AF-S DX NIKKOR 10-24MM F/3.5-4.5G ED is supplied with 77-mm snap-on front lens cap LC-77, rear lens cap LF-1, bayonet hood HB-23 and flexible lens pouch CL-1118.

The AF-S DX NIKKOR 10-24MM F/3.5-4.5G ED will be on sale from May (TBC) with an MSRP guide price of EUR849.

LUMIX G VARIO HD 14-140mm/F4.0-5.8 ASPH./MEGA O.I.S.

A New Micro FourThirds Digital Interchangeable Lens
LUMIX G VARIO HD 14-140mm/F4.0-5.8 ASPH./MEGA O.I.S.
With Silent Design for HD Movie Recording

March 3, 2009: Panasonic today unveiled a standard interchangeable zoom lens called the LUMIX G VARIO HD 14-140mm/F4.0-5.8 ASPH./MEGA O.I.S. as a new member of the LUMIX G Micro System. The new LUMIX G lens incorporates an inner focus direct-drive linear motor for focusing, which enables smooth, silent operation of its fast and accurate contrast AF system, for use in both photo and movie recording. Adopting the Micro Four Thirds System standard, the new lens offers a wide and long zoom range of 14-140mm (35mm camera equivalent: 28-280mm) to suit a large variety of shooting situations, from scenery to portraits or telephoto shots, in a surprisingly compact and lightweight body.

The new lens system uses four aspherical lenses and two ED lenses to achieve dramatic downsizing despite its powerful 10x optical zoom, while minimizing distortion and chromatic aberration. Panasonic's Mega O.I.S. (Optical Image Stabilizer) suppresses the blurring that is commonly caused by hand-shake, making it easy to shoot clear shots even at telephoto range or in dimly lit places without using a tripod.

When mounted on the DMC-GH1 Lumix G Micro System Camera, the new lens allows use of the advanced contrast AF system, which includes a Face Recognition function, for more convenient, more enjoyable shooting. Seven blades give the aperture a rounded shape that produces an attractively smooth effect in out-of-focus areas when shooting at larger aperture settings.

The new LUMIX G VARIO HD 14-140mm/F4.0-5.8 ASPH./MEGA O.I.S. lens also features a highly reliable metal mount, and uses multi-coated lens elements that minimise ghosts and flare to further enhance its optical performance.
