The Panasonic G-series is the longest standing name in the Micro Four Thirds system, and now, just a few months before Photokina, there's an update to the G3. The G5 stays pretty close to its roots, using a 16.05-megapixel sensor, but the Venus Engine it's coupled with has been totally revamped. It now has 3D and Multi-process noise reduction to help improve low-light performance. It also now has in-camera HDR, something that's becoming standard in most cameras.
