Nikon has released no less than five new additions to its range of CoolPix digital cameras. The cameras all use SD cards for additional storage capacity and connect to Macs using USB, while the top-of-the-range CoolPix S7c also offers WiFi connectivity.

Two new low-cost models – the 6-megapixel CoolPix L6 and the 7.2-megapixel CoolPix L5 – will be available exclusively through retailing stores.

The other three cameras are members of the compact ‘S’ series. The CoolPix S9 is a slimline model 2.4cm thick. It has 6.1-megapixel zoom and 3x optical zoom. The CoolPix S10 has the same resolution, but increases the optical zoom factor to 10x, and its swivelling lens mechanism allows you to take pictures from any angle.

The 7.1-megapixel Coolpix S7c has 3x optical zoom lens and features a large 3in LCD display, but its most interesting feature is the built-in wireless antenna, which allows you to transfer pictures straight onto any wireless-equipped Mac or PC.

The Skype VoIP software that lets you make voice calls from your computer to an ordinary phone line has been available for the Mac for some time. However, most of the handsets and accessories designed for use with Skype have been for PC users only. Now, though, you can starting to see a selection of Mac-compatible handsets.

SkypeStyle has just launched a number of Skype handsets for the Mac. The Cyberphone Mac is a USB handset that plugs into a USB port on your Mac and allows you to control Skype software and make calls through the handset. For the low price, you can go cordless with the Polar IP Atomic handset, or you can completely unplug from your computer with the Edge Core WiFi Phone, a mobile handset that can make Skype calls using any wireless network or hotspot.

Mac gadget specialists, Keyspan, are getting in on the act too, with their own Cordless VoIP Phone. The handset is a little pricey but includes a rechargeable battery so you won’t need to spend money on batteries.
