Nikon has introduced new digital still cameras with built-in wireless LAN (WiFi) adapters.

The WiFi connection can be used to transfer images to a computer or to a WiFi printer for printing. It's also possible to set the camera to automatically transfer each picture to the PC immediately after it's taken.

Communication can take place in two ways: in ad hoc mode a direct connection is established between the camera and a host device such as a personal computer; and in infrastructure mode the connection runs through a wireless, LAN base station to a device connected to the network.

8MP and 5MP WiFi snappers

The Coolpix P1 and P2 cameras, which will be available from later this month, are largely identical. The only significant difference between the two cameras is the resolution at which they take pictures. The P1 is an 8-megapixel camera while the P2 is a 5-megapixel model. In practice, this means full-resolution images from the P1 are 3,264 pixels by 2,448 pixels and those from the P2 are 2,592 pixels by 1,944 pixels.

It takes about eight seconds to transfer a full-resolution image from the P1 and about four seconds to do the same with the P2.

Other features include a 3.5x optical zoom and a 2.5-inch LCD (liquid crystal display) monitor. The on-screen menu can be switched between English, German, Spanish, French, Italian, Dutch, Swedish, Japanese, Simplified and Traditional Chinese, Korean and Russian. Both cameras measure 91mm-x-60mm-x-39mm and weigh 170 grams. Battery life is 180 shots for the P1 and 190 shots for the P2.

Both will be available in the U.S. later this month. The P1 will cost £519 and the P2 will cost £419 (including VAT).
