Nikon Coolpix S4

The Coolpix S4 is a brand of digital camera produced by Nikon. Its image sensor is a CCD with 6.0 million pixels. It has a 2.5 in thin-film transistor liquid crystal display device with 110,000 pixels. The S4 incorporates Nikon's popular swivel design which allows the addition of a powerful Nikkor 10X Optical zoom lens, yet retain a compact form. Other features include D-Lighting and Face-priority AF.

Nikon later released the Nikon Coolpix S10, which has a similar 10x swivel lens design as the S4, but with more advanced features such as vibration reduction and a lithium-ion battery.
