PMA Show - The Sigma Corporation is pleased to announce that FLD (“F” Low Dispersion) glass, which has a performance equal to fluorite glass, has been adopted and used in our new high performance lenses. FLD glass is the highest level low dispersion glass available with extremely high light transmission. This optical glass has a performance equal to fluorite glass which has a low refractive index and low dispersion compared to current optical glass. It also benefits from high anomalous dispersion. Using these characteristics gives excellent correction for residual chromatic aberration (secondary spectrum) which cannot be corrected by ordinary optical glass and ensures high definition and high contrast images.
In addition to the many interviews, attending various lectures, and receiving the information about (upcoming) product introductions, I went out to take photos with several new digital cameras. One of which is the Sigma DP2 compact camera, and although not a final production model, we are already able to provide you with a number of test photos which were made in Las Vegas with the Sigma DP2. The Sigma DP2 digital camera was first mentioned during the Photokina 2008. At that time, the process of the development of the Sigma DP2 camera was announced. This time, however, during the PMA 2009, it has become clear that Sigma is ready to launch the Sigma DP2 and deliver the new camera to its distributors.
Sigma announces the new Sigma 10-20mm F3.5 EX DC HSM lens. This super-wide angle lens has a maximum aperture of F3.5 throughout the entire zoon range. Its wide angle of view from 102.4 degrees produces striking images with exaggerated perspective. The maximum aperture of F3.5 is ideal for indoor shooting and it enables photographers to emphasize the subject. Two ELD (Extraordinary Low Dispersion) glass elements and a SLD (Special Low Dispersion) glass element provide excellent correction of color aberration. Four aspherical lenses provide correction for distortion and allow compact and lightweight construction. The Super Multi-Layer coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range.
Sigma Corporation is pleased to announce the new Sigma 18-50mm F2.8-4.5 DC OS HSM lens. This large aperture standard zoom lens incorporates Sigma’s original Optical Stabilisation function. This lens offers a large aperture of F2.8 at 18mm wide angle. This large aperture and anti-shale function is ideal for indoor photography and in low lighting condition. 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 anti-shake function. 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.
Sigma announces the new Sigma 50-200mm F4-5.6 DC OS HSM. This compact high-performance telephoto zoom lens incorporates Sigma’s own Optical Stabilizer function. The Sigma 50-200mm lens incorporates SLD (Special Low Dispersion) glass in the front lens group and is equipped with an inner focusing system to provide high image quality throughout the entire zoom range. The incorporation of HSM (Hyper Sonic Motor) ensures quiet and high-speed auto focus. The OS (Optical Stabilizer) function effectively eliminates the effects of camera shake so subjects can be easily and clearly seen in the viewfinder as well as in the image. It allows the use of shutter speeds approximately 4 stops slower than normal
This Sigma lens is the world’s first ultra telephoto zoom lens that offers a fast aperture of F2.8 at the 500mm focal length and F5.6 at the 1000mm. It covers widely used focal lengths from 200mm to 500mm and has a large aperture of F2.8 throughout the entire zoom range. The Sigma APO 200-500mm F2.8/400-1000mm EX DG lens can be used to create amazing image expression with various types of photography such as astrophotography, portraits, wildlife, sports. SLD (Special Low Dispersion) glass and three ELD (Extraordinary Low Dispersion) glass elements provide excellent correction for all type of aberrations. The super multi layer lens coating reduces flare and ghosting.
For Sigma, the latest Photokina has been an important event. Not only for them being a lens manufacturer but also a camera manufacturer. At that time Sigma introduced the Sigma SD14, a digital SLR camera based on the deviated Foveon X3 image sensor. Besides that Sigma introduced the DP1 digital compact camera that has been equipped with the Foveon image sensor. Not one of these cameras had reached the final stage then and the availability of the Sigma SD14 was even postponed. But at the PMA 2007 Sigma announced the availability of the Sigma SD14 digital SLR and the first results are starting to appear here and there on a users forum and on different web sites of the true Sigma lovers.
The Sigma Corporation is pleased to announce the launch of the new Sigma SD14 Digital SLR camera. The new Sigma SD14, powered by the 14 megapixels Foveon X3 direct image-sensor, can reproduce high definition images. The Sigma SD14 Digital SLR camera features four JPEG recording modes, large and bright pentaprism viewfinder with 98% coverage, a built-in flash with a Guide Number of 11, 5 point AF system, a large 2.5” 150,000 pixel resolution LCD monitor as well as high resolution and user friendly design. The durable shutter mechanism has a over 100,000 cycle life and is ideal for the demands of digital photography. Sigma introduced its first digital SLR camera, the Sigma SD9, to the market in October 2002.
