Who wants a phone with 25 days baterry life?

Speaking of Sigma, the company is now providing those of you with four-thirds format DSLRs (including popular models from Olympus and Panasonic) with another option for extreme wide-angle glass. The Sigma 10-20mm f/4-5.6 EX DC HSM, currently available in other standard mounts, provides a sufficiently wide (94.5 degrees) angle of view on four-thirds cameras.

With an hyper-sonic motor (HSM internal focusing system, the new lens, which provides an equivalent range of 20-40mm, promises fast, near-silent focusing, with a minimum focusing distance of just under 10 inches at all focal lengths.

At the other end of the range, the 70-200mm f/2.8 II EX DG HSM functions like a 140-400mm long telephoto unit on a four-thirds camera. Designed with multiple SLD and ELD lens elements to correct for optical faults, the 70-200mm's glass is also coated to reduce flare and ghosting.

Both lenses should be available in April. No word yet on US street pricing.
