10-20mm F4-5.6 EX DC HSM and 70-200mm f/2.8 II EX DG HSM for Four Thirds mount from Sigma
Release Issued by Sigma:

Sigma announce two new lenses for the Four Thirds System

10-20mm f/4-5.6 EX DC HSM
Super wide-angle zoom lens designed exclusively for digital SLR cameras now available in the Four Thirds fitting.

    • Compact and lightweight ultra wide-angle zoom lens
    • Special Low Dispersion (SLD) and aspherical lens elements
    • Inner focusing system
    • HSM (Hyper Sonic Motor) motor and full time manual focus
    • Minimum focusing distance of 24cm at all focal lengths

    The super wide-angle capability of the 10-20mm zoom makes it a very powerful tool for both indoor and landscape photography. The wide angle of view (94.5°at 10mm on Four Thirds cameras) offers broader perspective, and gives the photographer greater freedom of expression.

    Three SLD glass elements are employed for effective compensation of colour aberration, a common problem with super-wide angle lenses. One molded glass element and two hybrid aspherical lenses, offer excellent correction for distortion, as well as all types of aberration.

    This lens is equipped with an inner focusing system and HSM design providing quiet, high speed autofocus while offering full time manual focusing. It has a minimum focusing distance of 24cm (9.4”) at all focal lengths.

    The non-rotating lens barrel is eminently suitable for the petal shaped lens hood (included) and circular polarizing filters.
