HS50 Eye Fi

Noel only just seen your post. Wifi (eyefi) is something you set up through wifi devices. Ie internet connection or your laptop etc . You can select private and public access as well. Its a great way of backing up images immediatly as you can do this "live" ie take the shot and its sent to pc/interenet straight after been recorded to sd card. (Dont think it has raw support yet).

You do need an eye fi card in the camera . Cheers Paul UK
