Two new lenses for Sony and Pentax cameras

The Sigma Corporation is pleased to announce the launch of the new APO 50-150mm F2.8 EX DC HSM II lens and the new 70-200mm F2.8 II EX DG MACRO HSM lens for Sony and Pentax digital SLRs.

50-150mm f/2.8 EX DC HSM
Compact, large aperture telephoto zoom lens incorporating the latest optical technology.

• SLD glass elements and super multi-layer lens coating
• High image quality throughout the zoom and focusing range
• Inner focusing system
• HSM (Hyper Sonic Motor) motor and full time manual focus
• Compatible with Sigma APO Tele-Converters
  

This large aperture telephoto zoom lens is designed to match APS-C size image sensors and its compact, lightweight body provides freedom of movement and versatility. The minimum focusing distance of 100cm/39.4in. and the high-resolution power layout have improved the strength of the lens in close-up photography.

This lens offers a large aperture of F2.8 and its large depth of field offers greater freedom of creative expression. It has a maximum aperture of F2.8. Four SLD glass elements are used for maximum correction of chromatic aberrations. The super multi-layer lens coating reduce flare and ghosting and ensure sharp images throughout the entire zoom range. The lens design incorporates an inner focusing and inner zooming system. As the overall length of the lens does not change during focusing and zooming, convenient handling is ensured. The HSM (Hyper Sonic Motor) system allows quiet and high-speed auto focusing with full time manual focus override by just rotating the focusing ring.

The addition of the optional 1.4x EX DG APO or 2x EX DG APO Tele Converters produce a 70-210mm F4 AF tele-zoom lens and a 100-300mm F5.6 AF ultra-telephoto zoom lens respectively


70-200mm f/2.8 II EX DG HSM

Large aperture zoom lens with a minimum focusing distance of 100cm, and improved optical performance.

• Improved optical performance
• Two SLD and three ELD glass elements
• Super multi-layer coating reduces flare and ghosting
• HSM ensures quiet, high speed autofocus

This large aperture zoom lens has improved optical performance and retains close-up ability with a minimum focusing distance of 100cm and maximum magnification ration of 1:3.5. This lens is suitable for taking all type of subjects such as portraits, landscape, and close-up pictures.

Two SLD (Special Low Dispersion) and three ELD (Extraordinary Low Dispersion) glass elements provide excellent correction for all types of aberrations. High image quality is assured throughout the entire zoom range. The super multi-layer coating reduces flare and ghosting.

This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF as well as full-time manual focusing capability. The lens design incorporates an inner focusing and inner zooming systems. The overall length of the lens does not change during focusing and zooming, ensuring convenient handling.

A removable tripod collar (TS-21) is included as a standard component.

Two new lenses for four-thirds

10-20mm f/4-5.6 EX DC HSM

Super wide-angle zoom lens designed exclusively for digital SLR cameras now available in the Four Thirds fitting.

• Compact and lightweight ultra wide-angle zoom lens
• Special Low Dispersion (SLD) and aspherical lens elements
• Inner focusing system
• HSM (Hyper Sonic Motor) motor and full time manual focus
• Minimum focusing distance of 24cm at all focal lengths
  

The Sigma Corporation is pleased to announce the 10-20mm F4-5.6 EX DC HSM for the Four Thirds fitting.The super wide-angle capability of the 10-20mm zoom makes it a very powerful tool for both indoor and landscape photography. The wide angle of view (94.5�at 10mm on Four Thirds cameras) offers broader perspective, and gives the photographer greater freedom of expression. Three SLD glass elements are employed for effective compensation of colour aberration, a common problem with super-wide angle lenses. One molded glass element and two hybrid aspherical lenses, offer excellent correction for distortion, as well as all types of aberration.

This lens is equipped with an inner focusing system and HSM design providing quiet, high speed autofocus while offering full time manual focusing. It has a minimum focusing distance of 24cm (9.4�) at all focal lengths.

The non-rotating lens barrel is eminently suitable for the petal shaped lens hood (included) and circular polarizing filters.

Nikon D3 Digital SLR Review

Nikon D3 Review - In August 2007, Nikon unveiled the D3 Pro DSLR. A camera so monstrous, we should technically be scared of it. Ian Andrews puts it to the test.

Along with the recently reviewed D300, Nikon also announce a new Flagship to their digital camera range, the D3. The announcement raised both eyebrows and sighs of relief, being Nikon's first venture into �full frame' digital photography. Ian Andrews takes a look to see what all the hype is about:

Nikon D3 specifications:

* Sensor: CMOS - 12.8Mp
* Image Size: 4,256 X 2,832 Pixels
* Lens: Takes all Nikkor lenses
* Focus: Auto/Manual
* Exposure: Program/AP/SP/M
* Metering: 3D Matrix/CW/Spot
* Monitor: 3in LCD
* Movie Mode: No
* Storage: CF I/II
* Batteries: Li-ion Battery EN-EL4a
* AC Adaptor: Optional
* Video Output: Yes
* Size/Weight: 160x157x86mm - 1.07kg
* Transfer: USB2.0

Launched at �3399, the D3 pitches into the marketplace with its only genuine competitor being the Canon 1DmkIII at around �2600 although that is an APS-H sized sensor with a slightly lower pixel count.
