Press Release:
The Sigma Corporation are pleased to announce the 10-20mm Sigma 10-20mm f/4-5.6 EX DC HSM for the Four Thirds fitting.

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 moulded 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 (9.4in) at all focal lengths.

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