While prototypes were on display at the PhotoPlus Expo last fall, Canon has finally made the massive EF800mm f/5.6L IS USM and EF200mm f/2L IS USM lenses a reality. Both lenses carry Canon's L moniker and sport the putty colored finish that demark the cream of Canon's crop. Both lenses include Canon's optical image stabilization, as well as fluorite and UD (ultra low dispersion) lens elements to combat chromatic aberration, and includes moisture and dust resistant seals.
Compared to Canon's old EF200 f/1.8L USM, the new EF200 f/2 sacrifices a … Read more

There are so many makes and models of video glasses on the market that we lost count of them long ago. But one that was launched at Macworld this week may be worth mentioning, for the famous name associated with it if nothing else.
Expert photographers may debate the quality vs. hype of Carl Zeiss lenses, but the companies that use them in their products clearly think the brand packs plenty of marketing muscle--just ask Sony, which touts them every chance it gets for its cameras. So it makes sense that the German company would want to cash in on … Read more
I have had a pet interest in the 3D photography technology called stereoscopy ever since my mom gave me a stereoscope of 19th century design for some boyhood birthday. Although the technology remains a small niche of photography, it is being adapted to the digital age.
I recently came across the Loreo 3D Lens in a Cap, a stereo lens that works on most film or digital SLRs. It's a 38mm lens with an f/11 of f/22 aperture that takes two images of the same scene from slightly different perspectives.
With stereoscopy, your brain can reconstruct depth … 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
Japanese lensmaker Tokina announced two lenses Friday, an 11-16mm wide-angle zoom and a 35mm fixed-focal-length lens. (Update: Sorry for the extra word earlier--the second lens is indeed fixed at 35mm.)
Both models have relatively fast f/2.8 apertures useful for low-light conditions, and both are designed to mount on Canon and Nikon digital SLR cameras with smaller image sensors, according to announcements on Tokina's Japanese Web site.
The AT-X 116 PRO DX 11-16mm F2.8 is scheduled to be available in February 2008 at a cost of 90,000 yen, or about $810. It weighs 560 grams.

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
