The sensor-shift stabilization of the Olympus E-PL2, combined with the fast F2.8 aperture of the Sigma 30mm F2.8 EX DN allowed me to make this sharp shot of my daughter’s hand while she slept with a 1/13 shutter speed at ISO 400. With a 5.6 aperture on a kit micro four thirds lens, you’d either have to slow the shutter down to ⅓ second and risk a blurred frame, or crank the ISO to 1600 and add a lot of noise to create an equivalent exposure.
