The Sony VCL-DH1757 is a screw-on telephoto accessory lens made exclusively to work with their Cyber-shot DSC-HX1 camera. This is a high-grade, 5-element optical design which will provide excellent resolution even at the edges of the images, and is perfect for use whenever you'd wish to be closer to your subject but are limited to a further distance (such as at a spectator sporting event). The VCL-DH1757 increases the effective focal length by a factor of 1.7x.
