Last update: Review & Sample Photos @ FourThirdUser (added on 14 August’07)

Sigma has launched the new Sigma 105mm F2.8 EX DG Macro for Four Thirds lens, a large aperture macro lens enables you to shoot up to 1:1 life size close-ups optimized specially for digital SLR cameras. The lens featuring Super Multi Layer (SML) coating reduces the ghost caused by reflections from the surface of digital image sensors, and a “Focus Limiter Switch” that limits the AF range so improving the speed and accuracy of autofocus.

Sigma 12-24mm f/4.5-5.6 EX DG HSM is the world’s widest rectilinear lens for a 35mm SLR. The previous widest lens was Nikon’s 13mm f/5.6 AI-s manual focus lens which would cost you at about $15,000. The Sigma 12-24mm f/4.5-5.6 has Four Special Low Dispersion (SLD) glass elements for effective compensation of color aberration, which is a common problem with super-wide angle lenses. Two pieces of molded glass and three aspherical lenses, including two molded glass aspherical lens elements, offer excellent correction for linear distortion as well as all types of aberration.

This lens is quite big, but amazingly it is not heavy at all. With Canon EOS 5D, the Sigma 12-24mm f/4.5-5.6 EX DG is perfectly well-balanced. It’s also sturdy and cosmetically good in crackle-gray finish with heavily ribbed, rubberized, smooth-turning zoom and focus rings.
