Nikon has been experimenting with Wi-Fi-equipped cameras for a few years now. Not very long ago, Nikon introduced Wi-Fi in its ultracompact 7-megapixels Coolpix S50c. The latest Coolpix S51c continues this trend and incorporates an 8-megapixels CCD sensor, a 3-inch, 230,000-pixel LCD, sensitivity of up to ISO 1,600, and optical image stabilization.

What's new

The Nikon Coolpix S51c also has Nikon's D-Lighting to compensate for imperfect exposures after the fact, as well as Face Priority AF to help make sure that the camera focuses on your subject's faces, instead of a tree or some national monument in the background. It also includes Nikon's usual compliment of in-camera editing features so you can fix problems, such as red-eye, after you snap a picture.

Much like last year's model, the S51c lets you email images straight from the camera as long as you can connect to a compatible Wi-Fi hot spot. Since the S51c won't include any way to accept the terms of service of many public Wi-Fi hot spots, you'll need access to a private wireless router--though the camera will let you enter a security code if the router you're using is secure. Nikon is also starting its own photo-sharing Web site called myPicturetown and will include 2GB of free storage space with the Coolpix S51c.

If Wi-Fi connectivity doesn't float your boat, Nikon is also introducing the S51, which has all the same specs as the S51c, but doesn't include the Wi-Fi connectivity or the Wi-Fi associated freebies.
