In fact, the NEX-VG20 enjoys the benefits of a number of advancements over its direct predecessor, the VG10. It can now shoot HD (1920 x 1080) video in AVCHD at both 24p and 60p framerates (the VG10 could only shoot 30p), plus its stills see a resolution boost up to 16.1 megapixels. Also, the VG10 could only take stills in JPEG format, whereas the VG20 can save images in both JPEG and RAW formats. Other improvements include a remote control and the direct copy ability, which allows users to connect and record directly to an external hard drive.
As for high quality sound, Sony has that in spades with the VG20, which sports a quad capsule spatial array stereo microphone. With improved directional pickup, this new microphone supports stereo and 5.1 channel surround sound with audio level control.
