It's not much of an update, but how much could Olympus really throw at
the 12.3 megapixel E-PL1 if it hoped to maintain the title of the
world's lightest interchangeable lens camera? The new E-PL1S Micro
Four Thirds shooter features an ISO bump from 3200 to ISO6400 and new
BLS-5 battery that complies with a new rechargeable lithium-ion safety
standard. Combined, the kit weighs just just 454 grams (342 grams for
the body) when bundled with a 112 gram M.ZUIKO DIGITAL 14-42mm
F3.5-5.6 II lens -- a weight that includes the battery and SDCH memory
card. Look for the two to flutter onto retail shelves in April in
choice of red, white, or black (with silver lenses) for about ¥
60,000 ($723) or ¥80,000 ($964) with a M. ZUIKO DIGITAL ED
40-150mm F4-5.6 lens.
