The DMC-TZ30 incorporates a 20x optical zoom LEICA DC lens from 24 mm ultra wide-angle, featuring Nano Surface Coating technology that minimizes ghosts & flaring. The lens system makes the units overall length short to fit in the compact body despite its versatile zoom range. The 20x optical zoom increases its power to 40x equivalent with the Intelligent Zoom. This is an extensive zoom function using digital zoom with minimum deterioration of image quality thanks to the Intelligent Resolution technology.
