Carl Zeiss C Biogon T* 2,8/35 ZM Lens

The New Carl Zeiss C Biogon T* 2,8/35 ZM Completes Any Compact Photography Equipment

As the latest member of the ZM lens family, the C Biogon T* 2,8/35 ZM lens is the perfect addition to your light, mobile photo equipment. The C Biogon T* 2,8/35 ZM will inspire you with perfect images, even at full aperture. Together with the compact C Biogon T* 4,5/21 ZM, it creates the ideal equipment for a wide range of applications such as documentation and architecture photography.

The “C” in the title indicates another outstanding feature: rather unusual for a lens of this performance class, its moderate speed of 1:2.8 permits an exceptionally compact construction. The symmetrical Biogon construction with 7 lens elements in 5 groups allows for practically distortion-free images.
The ZM lens series from Carl Zeiss is suitable for cameras with M-bayonet. As with the other lenses in this line, the C Biogon T* 2,8/35 ZM features an intuitive operating concept, a robust all-metal frame and a precise, noticeable click in 1/3 aperture stops.
Delivery of this lens is scheduled to begin in mid 2008

Nikon PC-E Nikkor 24mm f/3.5D ED

Wide-angle NIKKOR lens with Perspective Control

Nikon’s high-performance PC (Perspective Control) lens, PC-E NIKKOR 24mm f/3.5D ED, is equipped with a tilt/shift mechanism to give photographers the flexibility to manipulate image perspective, distortion and focus. As both a special-purpose lens and high-performance wide-angle lens, the new PC-E NIKKOR 24mm f/3.5D ED lens represents a significant new addition to the legendary NIKKOR lens family.
The PC-E NIKKOR 24mm makes use of a special mount that enables up to ±11.5mm shift and ±8.5° tilt for perspective control. Shift and tilt are adjusted while referring to the scales provided with gradations at 1mm or 1° intervals. The lens optics can be rotated up to 90° right or left for perspective control adjustment and click-stops are provided every 30°.
The lens aperture can be preset using the aperture ring and the aperture stop-down button. For easy depth-of-field confirmation, it remains stopped down until the button is pressed again. Auto aperture control is also available for SLR models compatible with an electromagnetic diaphragm (Nikon D3 and D300).
In addition to the primary perspective control photographic applications such as architecture and interiors, this lens can also be used for any subject where a 24mm wide-angle lens is appropriate. With a closest focusing distance of only 0.21m and a maximum reproduction ratio of 1/2.7, it is an excellent choice for close-up photography.
Nikon’s original state-of-the-art optical features and technologies are incorporated into the PC-E NIKKOR 24mm for superior picture quality. Nikon’s exclusive Nano Crystal Coat dramatically reduces ghosting and flare caused by internal reflections and three ED glass elements minimize chromatic aberration for higher-resolution, higher-contrast images. Three aspherical lenses effectively correct spherical aberration and coma, while a rounded nine-blade diaphragm opening gives out-of-focus background elements a more natural appearance. The PC-E NIKKOR 24mm offers exceptional optical performance, even at maximum shift settings.
PC-E NIKKOR 24mm f/3.5D ED Features Highlights
  • Wide shifting and tilting range (shift: ±11.5mm; tilt: ±8.5°)
  • ±90° lens revolving capability for versatile tilt/shift effects
  • Maximum reproduction ratio of 1/2.7 (at 0.21m)
  • Three ED-(Extra-low Dispersion) glass elements provide superior sharpness and colour correction by effectively minimizing chromatic aberration
  • Three aspherical lens elements minimize various types of lens aberration
  • Nano Crystal Coat virtually eliminates internal lens element reflections, effectively reducing ghosting and flare
  • High-performance Nikon Super Integrated Coating delivers superior colour reproduction while substantially reducing ghosting and flare
  • Rounded nine-blade diaphragm for more natural appearance of out-of-focus image elements
  • Lens aperture can be preset using an aperture ring and the aperture stop-down button
  • Auto aperture control with electromagnetic diaphragm is possible with the Nikon D3 and D300

Nikon Lens AF-S DX NIKKOR 16-85mm

Compact 5.3x zoom DX-NIKKOR lens with SWM and VR II

Nikon's AF-S DX NIKKOR 16-85mm wide ratio zoom lens featuring Silent Wave Motor (SWM) and Nikon’s Vibration Reduction (VR) II is an ideal lens for an extensive range of shooting scenarios, including indoor-outdoor events, streetscapes, portraits and scenery. When mounted on any DX-format Nikon digital SLR camera, the picture angle is equivalent to a 24 to 127.5mm focal length in 35mm format.

The ultra-compact SWM built into the lens body ensures fast, quiet and accurate autofocus operation and complements the compact, lightweight design for superb handling. With dimensions of only Ø72 x 85mm, this new lens is ideal for general photography or specialists in travel and nature photography.

Nikon's VR II, specifically engineered for each NIKKOR lens, provides photographers with the ability to shoot at shutter speeds up to four stops* slower than would otherwise be possible, minimizing image blur caused by camera shake. This enables dramatically sharper handheld shooting at dusk or at night, or even in poorly lit interiors. Nikon’s VR function is incorporated and designed specifically for the lens, it provides state-of-the-art image sharpness capacity and a stable viewfinder image for accurate framing.

*As determined in Nikon performance tests

The new high-performance optical system has been optimized for Nikon digital SLRs. Two ED glass elements and three aspherical lenses deliver higher resolution, high-contrast images while minimizing chromatic aberration. A rounded seven-blade diaphragm opening gives out-of-focus background elements a more natural appearance. Nikon’s Super Integrated Coating ensures outstanding colour balance and reproduction while greatly reducing ghosting and flare.

The AF-S DX NIKKOR 16-85mm f/3.5-5.6G ED VR II is a significant addition to Nikon’s DX-NIKKOR lens line-up and is certain to become a favourite of photographers seeking a wide-ratio zoom with exceptional wide-angle capability and a telephoto perspective ideal for portraiture.

Notes:DX-NIKKOR lenses are engineered and optimized for use on Nikon DX-format and FX-format digital SLR cameras. When mounted on an FX-format digital SLR, the camera’s DX-Crop Mode is automatically engaged, altering the image capture area accordingly. DX-NIKKOR lenses are not compatible with 35mm [135] or IX240 [APS] format film cameras.

AF-S DX NIKKOR 16-85mm f/3.5-5.6G ED VR II Features Highlights

ZUIKO DIGITAL interchangeable lenses are specifically designed to maximize the performance potential of the image sensors in “Four-Thirds System” digital SLR cameras. Newly announced ZUIKO DIGITAL ED 40-150mm F4.0–5.6 lens is a lightweight, ultra-compact telephoto zoom lens that offers outstanding value.

ZUIKO DIGITAL ED 40-150mm F4.0–5.6 is the lightest (220g) and smallest lens in its class*, and boasts the shortest minimum shooting distance (0.9m). Its wide zoom range is equivalent to 80–300mm on a 35mm camera, and its Four-Thirds System design assures outstanding portability that makes interchangeable lens photography easier. (*) as an interchangeable telephoto zoom lens covering telephoto ranges over 200mm: 35mm equivalent (as of November 13th, 2006, by Olympus study)

Main Features

・ Lightweight and Ultra-Compact Design
ZUIKO DIGITAL ED 40-150mm F4.0-5.6 uses ED (Extra-low Dispersion) and high-performance glass elements and an optimized zoom range to ensure outstanding performance and portability. Packing the equivalent of 300mm telephoto power in a barrel only 72mm long, and weighing just 220g, it makes it easy to enjoy true telephoto shooting in the field. The lens’s 3.8x zoom covers a wide range of focal lengths, and offers performance equivalent to 80-300mm on a 35mm camera.

・ Excellent Close-Focusing Capability
An inner focusing system assures that lens length remains constant, and provides close focusing from 90cm at any focal length.

Other Features

・ Superior Imaging Characteristics
ED and high refractive index glass elements are used to minimize chromatic aberration, coma flare, and image curvature. Sharp, high-contrast imaging is achieved at the outer periphery of the lens at all focal lengths. Advanced technologies for high image quality include multi-coating to reduce ghosting and flaring in backlight, and the use of a circular iris to achieve smooth, soft, background defocusing.

・ Filter Support
A non-rotating mount ensures that filters do not rotate when the lens is focused, making it much easier to shoot when using polarizing filters.

The ZUIKO DIGITAL ED 40-150mm F4.0-5.6 is scheduled to go on sale in Japan on November 23, 2006.
