Cyber-shot is a line of Sony digital cameras which are known for their InfoLithium battery pack and Carl Zeiss lenses. There are actually 15 series of models of Cyber-shot cameras of which the W series is one. These cameras use wide angle lenses with special coating for panoramic shots. The W series, in turn, includes 20 different variations.
Of these, the DSC W210, DSC W220, and DSC W270 are of identical dimensions and thus all fit into the Sony MPK-WEB Marine Housing for Cyber-shot Digital Cameras. Although the DSC WX1 is slightly smaller, it is also compatible with the marine housing.
All of these Cyber-shot cameras except for the WX1, boast of a 12.1-megapixel CCD image sensor assuring high-resolution photos. For the W210 and W220, this is coupled with a Carl Zeiss 4x optical zoom which is the equivalent of a 30 – 120 mm lens in the 35 mm format. The W270 has a slightly wider range at 5x starting from 28 – 140 mm. With these zoom ranges, you can shoot wide landscape vistas as well as up close and personal portraits. The WX1, on the other hand, has a 10.2-megapixel image sensor, with a lens identical to that of the W270.
The Sony MPK-WEB Marine Housing for Cyber-shot Digital Cameras is the diving gear of the DSC W210, DSC W220, and DSC W270. It can take them to a depth of 40 m to shoot underwater landscapes and marine life. A special o-ring is supplied to resist water even under pressure.
A diffuser in front of the camera’s built-in flash can be used underwater. If, however, it proves insufficient to supply needed lighting, it can also be used to trigger an external slave strobe. It is compatible with the HVL-ML20M underwater light. This, however, requires the VCT-MP1K arm. An LCD hood is installed over the monitor to shade it from light that could affect the display.
The marine housing has dimensions of 148 W x 112 H x 89 D mm.
