Posted by: Ilse Jurrien Tuesday 26th, September 2006

Sigma launched today a new Four-Thirds system compatible, compact telephoto zoom lens; Sigma APO 135-400mm F4.5-5.6 DG.

The very latest lens coating technology and lens design reduce flare and ghosting, a common problem with digital cameras. This lens uses one aspherical lens and three Special Low Dispersion (SLD) glass elements for excellent correction of various aberrations.
