Sigma SD15

Sigma dropped a bunch of new pro glass at today's PMA Sneak Peek event in Anaheim, CA.

The new Sigma lenses include a 85mm F/1.4; 70-200 F/2.8; and 8-16mm wide-angle lens.

The company also showed off (right image) a prototype of its long-awaited SD14 digital SLR. The 14-megapxiel DSLR, which uses a Foveon X3 imaging sensor, was first introduced at photokina 2008 though Sigma has still not set an availability date or pricing for the camera.

Details on the new lenses in the press releases below.


PRESS RELEASES


SIGMA 8-16mm F4.5-5.6 DC HSM
The Sigma Corporation is pleased to announce the new Sigma 8-16mm F4.5-5.6 DC HSM.  This is the first ultra wide zoom lens with a minimum focal length of 8mm, designed specifically for APS-C size image sensors. This lens has an equivalent angle of view of a 12-24mm lens when used on digital cameras with an APS-C size image sensor.  The wide-angle of view from 121.2 degrees* produces striking images with exaggerated perspective, enabling photographers to emphasize the subject.  Four FLD (“F” Low Dispersion) glass elements, which have the performance equal to fluorite glass, compensate for color aberration. One hybrid aspherical lens and two glass mold elements give excellent correction for distortion and astigmatism. Incorporating an inner focusing system, the lens produces high definition images throughout the entire zoom range. The Super Multi-Layer Coating reduces flare and ghosting while superior peripheral brightness ensures high contrast images throughout the entire zoom range.  This lens incorporates HSM (Hyper Sonic Motor), ensuring quiet and high speed AF as well as full-time manual focus capability. It has a minimum focusing distance of 24cm throughout the entire zoom range which allows photographers to emphasize the subject by creating exaggerated perspectives. This lens has a compact construction with an overall length of 105.7mm and a maximum diameter of 75mm.

SIGMA 85mm F1.4 EX DG HSM V

The Sigma Corporation is pleased to announce the new Sigma 85mm F1.4 EX DG HSM. This large aperture medium telephoto lens optimized for use with digital SLR cameras features a focal length of 85mm, ensuring a natural perspective. The large aperture of F1.4 is especially ideal for portrait and low light photography. When used on digital cameras with an APS-C size image sensor, the lens effectively becomes a 127.5mm F1.4 lens. One SLD (Special Low Dispersion) glass element and one glass mold element give excellent correction for all types of aberrations and ensure superior optical performance. This lens is equipped with a rear focus system that minimizes fluctuation of aberration caused by focusing. The Super Multi-Layer Coating reduces flare and ghost even in backlight photography. Incorporating HSM (Hyper Sonic Motor), this lens provides quiet and high speed AF as well as full-time manual focus capability. It features a minimum focusing distance of 85cm and a maximum magnification 1:8.6. This lens has a round 9 blade diaphragm which creates an attractive blur to the out of focus images.



This lens is supplied with a Petal-type hood to block out extraneous light. For digital cameras with an APS-C size image sensor, a dedicated hood adapter, which expands the length of the lens hood, is supplied and enables the hood to block out extraneous light more effectively.

SIGMA APO 70-200mm F2.8 EX DG OS HSM
The Sigma Corporation is pleased to announce the new Sigma APO 70-200 F2.8 EX DG OS HSM. This large aperture telephoto zoom lens incorporates Sigma’s original Optical Stabilizer function.

The lens covers a medium telephoto range of focal lengths from 70mm to 200mm and has a large maximum aperture of F2.8 throughout the entire zoom range. The OS (Optical Stabilizer) function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible.  For Sony and Pentax mount, the built-in OS function of this lens can be used even if the camera body is equipped with an image sensor shift anti-shake system.  As compensation for camera shake is visible in the view finder, the photographer can easily check for accurate focus and ensure there is no subject movement.  Two FLD (“F” Low Dispersion) glass elements, which have the performance equal to fluorite glass, and three SLD (Special Low Dispersion) glass elements provide excellent correction of color aberration. High image quality is assured throughout the entire zoom range and an optimum optical power layout provides superior optical quality in all shooting ranges from close-up to infinity. Super Multi-Layer Coating reduces flare and ghost.  This lens incorporates HSM (Hyper Sonic Motor), ensuring a quiet and high speed AF as well as full-time manual focus capability.  The lens has a minimum focusing distance of 140cm (55.1”) throughout the entire zoom range and a maximum magnification ratio of 1:8.  The rounded 9 blade diaphragm creates an attractive blur to the out of focus images.  This lens is equipped with a Petal-type hood.  For digital cameras with an APS-C size image sensor, a dedicated hood adapter, which expands the length of the lens hood, is supplied.

SIGMA 17-50mm F2.8 EX DC OS HSM

The Sigma Corporation is pleased to announce the new Sigma 17-50mm F2.8 EX DC OS HSM.This large aperture standard zoom lens is designed for digital SLR cameras and incorporates Sigma’s efficient OS function.  It is a compact lens with an overall length of just 91.8mm (3.6”). This lens covers a focal length from 17mm wide angle and offers a large aperture of F2.8 throughout the entire zoom range, making it ideal for many types of photography such as portraiture and landscapes.  The OS (Optical Stabilizer) function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible.  For Sony and Pentax mount, the built-in OS function of this lens can be used even if the camera body is equipped with an image sensor shift anti-shake system. As compensation for camera shake is visible in the viewfinder, the photographer can easily check for accurate focus and ensure there is no subject movement.  Two FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite glass, plus two glass mold and one hybrid aspherical lens, provide excellent correction for all type of aberrations.  The Super Multi-Layer Coating reduces flare and ghost.  This lens has superior peripheral brightness and provides sharp, high contrast images even at the maximum apertures.  High image quality is assured throughout the entire zoom range.  Incorporating HSM (Hyper Sonic Motor), the lens provides fast and quiet AF.  The lens has a minimum focusing distance of 28cm (11”) throughout the entire zoom range and a maximum magnification ratio of 1:5.  The rounded 7 blade diaphragm creates an attractive blur to the out of focus images.  The inner focusing system eliminates front lens rotation, making the lens particularly suitable for use with the supplied petal-type lens hood and circular polarizing filters.
