The VDR-D50's 42x optical zoom lens has the power you need to take dramatic closeups or get remarkable shots of even distant subjects. But with long-distance zoom shots, even a tiny bit of hand shake has a huge effect on picture quality. That's where Panasonic's Advanced Optical Image Stabilization (O.I.S.) comes in, suppressing the effects of hand shake as you shoot. The system uses gyrosensors to detect hand shake, then shifts a lens and adjusts the optical axis to compensate. This all happens a remarkable 4,000 times per second. And because the system is optical, no image quality is lost. Thanks to Advanced O.I.S., the images you capture look incredibly clear, sharp and blur-free even at high zoom levels.For quick and easy operation, this DVD camcorder automatically finds a blank section on the disc when you start shooting. And with multi-format recording, you can choose whichever type of disc works best with your DVD player or recorder. When you finish shooting, just take the disc from the camcorder and slip it right into your DVD player or recorder. There's no need to connect any cables and you can start viewing your memories right away.You can either insert the DVD disc right into your PC or use the included USB cable to connect the camcorder to your PC and transfer the motion-image data that way. Then with the included VideoCam Suite 1.0 software, you can easily put scenes in a different order and delete the ones you don't want. When you're finished with your video production, you can resave the edited version onto an SD memory card or a DVD disc.
