We took an early model of the Panasonic Lumix DMC-GF5 for a spin around Madison Square Park.
This ISO 160 sample from the Panasonic Lumix DMC-GF5 shows pretty good exposure in high-contrast light. This is at the default color settings, which (like most cameras) tend to push the contrast and saturation a little. I usually prefer the camera's neutral setting.
While there are some JPEG artifacts and some processing-induced softness that might get fixed by the time the camera ships, the midrange-sensitivity images don't show any hot pixels in the deep blacks, and overall look pretty good as long as you don't pixel-peep.
