Internally the G10 shares most of the same features as the G2. It has the same Four-Thirds format 12.1-megapixel Live MOS sensor, measuring 17.3 x 13.0mm, the same as the sensors in full sized Four-Thirds DSLRs. Like the other G-Micro cameras the G10 has no internal image stabilisation, but some of the system lenses do feature Panasonic's Mega OIS optical stabilisation technology, although these are quite expensive. The high quality Leica-branded 14-50mm f/2.8-3.5 Mega OIS standard zoom is around £770, and the f/4.0-5.6 45-200mm telephoto zoom is £275.
Like the G2 the G10 is equipped with Panasonic's Intelligent Resolution technology, which is the latest attempt to get us to like the idea of digital zoom. It enhances edge contrast and detail on digital zoom shots, and does improve image quality somewhat, but it's still no substitute for a proper telephoto lens.
Unlike the G1, the G10 has a video recording mode, but again this is a slightly cut-down feature. It records at a resolution of 1280 x 720 pixels and 30 frames a second, with mono audio recoded via a single internal microphone, but unlike the G2 it does not have the option to plug in a stereo microphone. Video is recorded in Motion JPEG format rather than the superior AVCHD format of the G2 and GH1. Picture quality is pretty good though, and the microphone has automatic wind cut, so the sound quality isn't bad either.
