Over the holiday weekend we spent some time shooting with Panasonic's newest mirrorless camera, the Lumix DMC-G7. We put its new 16MP sensor to the test along with an improved AF system at the racetrack - the Indianapolis Motor Speedway, to be precise. Under the bright conditions, we were shooting mainly at the camera's using lower ISO settings. A full gallery is on the way (hopefully also including some Raw conversions), but in the meantime buckle your seatbelt and take a look at some high-octane sample images.
