Konica Minolta withdraw from camera business
http://www.dpreview.com/news/0601/06011901...aminoltaout.asp

Konica Minolta has long been a leading company in photo imaging business covering wide range of imaging from input to output. In addition, we have provided inspiring products and services by fusing our unique technologies.

In camera business, we have expanded picture-taking opportunities by developing innovative technologies such as the world’s first autofocus cameras. In 1962, our camera, well-accepted for its high reliability, boarded on the US’s first manned spaceship “Friendship 7.” Also, ever since introduction of the world’s first body-integral autofocus SLR camera, Maxxum/Dynax series, in 1985, SLR cameras have become more popular among picture-takers, and we have succeeded in selling 16 million units of interchangeable lenses since then.

However, in today’s era of digital cameras, where image sensor technologies such as CCD is indispensable, it became difficult to timely provide competitive products even with our top optical, mechanical and electronics technologies.

In photo business, represented by the silver-halide photography such as color film and color paper, we have produced Japan’s first photographic paper in 1903, and Japan’s first color film in 1940, thus pioneering joy of photography for more than a century. In 1984, we introduced the world’s first compact washless photofinishing system known as a minilab system. The minilabs contributed to the expansion of worldwide photographic market by making photos closer to consumers and amazingly shortening delivery time.

However, traditional silver-halide photographic market is shrinking astonishingly by the surge of the worldwide digitization. In such a changing world, profits for camera and photo businesses worsened in recent years, and it became necessary to drastically reform business structure for the further growth of Konica Minolta. Ever since we decided and announced restructuring guidelines of our businesses on November 4, 2005, we have been considering practical and detailed plan, and we would like to announce our decision made today as follows:

Press Release:

Large aperture standard zoom lens designed specially for digital SLR cameras
Minimum focusing distance of 20cm,with an impressive maximum magnification of 1:2.3. at all focal lengths.
New design and multi layer lens coating reduce flare and ghosting.

The Sigma Corporation is pleased to announce the launch of the new 17-70mm F2.8-4.5 DC MACRO lens.The lens is ideally suited for a wide variety of subjects and is designed specifically for digital SLR cameras featuring APS-C size image sensor.

This revolutionary lens has a minimum focusing distance of 20cm (7.9”) throughout the entire zoom range. A maximum magnification of 1:2.3 enables extreme close-up photography. An impressive achievement for a standard zoom lens. The new lens design and multi layer lens coating reduce flare and ghosting, a common problem with digital cameras. A Special Low Dispersion (SLD) lens and two aspherical lens elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range.
This lens offers a large F2.8 aperture at 17mm wide angle and yet it is compact, with an overall length of just 79mm (3.1”) and diameter 82.5mm (3.2”). Performance is superb, even in relatively low light conditions indoors or at dusk.

The lens design incorporates an inner focusing system, which ensures fast AF speed as well as preventing the front of the lens rotating, making it particularly suitable for use with circular polarizing filters and petal shaped lens hoods.
This lens is also equipped with a zoom lock that eliminates “Zoom Creep” during transportation.
