Firmware update for the lens?
It seems odd, even to me, a software engineer, to be updating the firmware in my camera lens – but its for real. Panasonic released firmware updates for several of their camera lenses, including the standard 14-42mm kit lens: 43 Rumors | Blog | Panasonic firmware update for four m43 lenses!.
The improvement is said to improve auto-focusing, image stabilization, and reduce potential focus noise when recording video. I have installed the update on my 14-42mm lens via the camera today, without any problems.
