With a 1.8" hard disk drive built-in, its lightweight compactness is not constrained by the size of videocassette or disc media, nor does it require a space-consuming loading mechanism. The redesigned image processor for Everio G series incorporates 6 digital noise reduction systems to improve the S/N ratio by about 30% (3dB) over previous models. The integrated MPEG-2 encoder features circuitry that reduces the block noise and mosquito noise that can occur with digital video recording formats. It's assurance that all of those Gigabytes of video and photos you shoot will offer the best picture quality available for each recording mode. The built-in flash or video light functions automatically so you can shoot brilliant images even in low light situations. The flagship model GZ-MG555 is equipped with both. GZ-MG555 is designed for serious shooting, but it's so easy you'll think it's fun!
