Sigma has delayed the release of its DP1 to revamp the high-end compact camera, but one thing that won't change is the Foveon sensor at its heart.
When Sigma said last week that it was changing the DP1's image processing "pipeline" to meet quality and performance goals and that the Japanese company "had to change some of the specifications that we had announced," I naturally wondered whether the changes might have evicted the image sensor.
Not so, according to Richard Turner, vice president of marketing and applications at the San Jose, Calif.-based start-up. … Read more
Sigma announced two higher-end telephoto lenses this week for digital SLRs with smaller image sensors.
One has a range of 70mm to 200mm and the other 50mm to 150mm, but both have a large f/2.8 aperture for faster shutter speeds in lower-light conditions and a hypersonic motor for quiet focusing. The lenses are designed for Canon, Nikon, and Sigma SLR cameras.
The two lenses highlight the growing sophistication of technology for digital SLRs with sensors smaller than a frame of 35mm film. Though Canon and now Nikon sell full-frame cameras, the vast majority of models sold use less … Read more
Sigma has delayed the debut of the DP1, a high-end compact camera with an unusually large image sensor, to redesign its image-processing technology.
The Japanese company had shown off the DP1 at the Photokina show in 2006 and later at the Photo Marketing Association show in March 2007, where it said it planned to ship the DP1 in the summer. The camera's sensor, made by start-up Foveon, is as large as the one used in Sigma's SD line of SLR cameras, offering the potential for much greater sensitivity and dynamic range than the much smaller chips typically used … Read more
Sigma announced two fisheye lenses Wednesday, one with a 4.5mm focal length and the other a 10mm model--for Canon, Nikon, and Sigma SLR camera owners who want to photograph extreme wide angle views.
Fisheye lenses capture light from an extremely broad angle, but produce distorted views of the world with parallel lines bowing outward. That distortion can be annoying, but many enjoy it as an artistic effect--think giant bulging faces in the foreground dominating tiny trees beyond--and scientists use some varieties of fisheye for precise measurements such as the sky's cloud cover.
But the digital SLR era has … Read more
Tamron will start shipping its image-stabilized 28-300mm lens on Monday--but only in Japan and for Canon SLRs, the company said.
The lens, formally called the AF 28-300mm F/3.5-6.3 Di VC, is one of a host of new image-stabilized superzoom lenses on the market. Nikon has said its 18-200mm model is its all-time bestseller. Sigma recently added its own 18-200mm competitor. And Panasonic, whose lenses are compatible with Olympus SLRs and vice versa, also offers a 14-150mm model, which is the same range when translated into 35mm camera terms.
Tamron had planned to release the lens in August, … Read more

Management's focus on innovation comes and goes in cycles. Right now, it is all the rage again (although it remains to be seen if that's still the case as innovation budgets may be cut when the looming recession hits the US), and the business press is covering it all across the board. Managing innovation is one of the most critical tasks companies face, and yet it remains one of the biggest challenges. Not only do companies need to come up with new ideas, but they also need to nurture a culture that consistently encourages and rewards innovation. If … Read more
