Sony Cybershot DSC G3 10MP Digital Camera comes with a picture resolution of 10.1 mega-pixels. A higher sensor resolution produces superior quality images. It uses Carl-Zeiss Vario-Tessar lens system with a 4x optical zoom. This indicates that the image can be enlarged to 4 times its original size without any adverse effect on the quality of the picture. The digital zoom offered by this camera is 8x, however the image clarity is affected when digital enlargement is used. Images can be previewed on the camera’s 3.5-inch LCD touch screen display.
