Its latest addition is the TZ10 with 12x optical zoom and a built-in GPS module. We got hold of a pre-production unit at the Panasonic Optical Seminar 2010 in Melbourne held for regional media and managed to form a pretty good idea of the TZ10's proposition. The TZ10 replaces the earlier TZ7. Both cameras share a great deal of similarities including a compact footprint, 25-300mm focal length, high-definition 720p video capture in either AVCHD or Motion JPEG format, and a 3-inch screen.
