The DCR-SR45 Handycam(R) camcorder is ready when you are, with a built-in 30GB Hard Disk Drive for storage and up to 20 hours of recording time (LP). A 2.7" Touch Panel LCD Monitor keeps all the controls at your fingertips, while a 40x Optical, 2000x Digital Zoom keeps all the action up close and personal. The DCR-SR45 brings simplicity back to video sharing. 1/8" Advanced HAD(TM) (Hole Accumulation Diode) CCD with 680K effective pixels provides stunning detail and clarity with exceptional video, up to 500 lines of horizontal resolution and still image performance. The optical zoom helps to bring the action close up from far away. In addition the Digital Zoom Interpolation means that extreme digital zooming is clearer, with less distortion than previous types of digital zooms. The 2.7" LCD display rotates up to 270 degrees for multiple viewing angles, as well as provides sharp, detailed images for monitoring or playback. Carl Zeiss Vario-Tessar lenses are designed specifically for compact camcorders, and utilize precision ground optics to maintain the sharpness and contrast found with larger lenses.
