Quesabesde.com is one of the first web site to publish a hands on preview with a number of sample photos including some high ISO testing samples. First published in masterchong.com at Olympus E-420 with Zuiko 25mm F2.8 Pancake Lens Sample Photo, here is a set of ISO200 to ISO1600 sample photos shot by them.
Judging from those samples above, Olympus which used to be notorious noisy images at anything above ISO400 seems to have improve their in camera noise reduction algorithm. ISO400 looks good, even ISO800 has little noise. I guess we shall expect usable noise setting at ISO3200 for their upcoming E-520 camera.
