The 16-MP sensor paired with the Venus Engine claims to have given the G7 an expanded dynamic range, higher sensitivity, and improved noise reduction. The G7 shoots at 8-fps, uses the same contrast AF system as the GH4 and can shoot down to -4EV. The AF Tracking has been updated to grab onto not only color, but also the size and motion of the object it is tracking, making it easier to stay locked on a quickly moving subject. A newly added feature in the G7 called Starlight AF gives shooters the ability to precisely focus on stars in the sky using the AF. The G7 has a max ISO of 25,600, a new max shutter speed of 1/16,000 sec and is compatible with UHS-11 SDXC/SDHC Memory cards.
