Digital cameras these days sport a feature we used to think isn’t too useful — WiFi. Nikon was one of the first few to actually include it in their compact models. But think about this, shooting an assignment on location, wouldn’t it be nice to directly preview your photos in a notebook for instantaneous review?
Now here comes the Eye-Fi, an SD memory card that adds WiFi connectivity to your camera. Yes, your old camera can still have WiFi just by using this card! Setup is fairly easy, though it works with your router only, and doesn’t connect to just any hotspot. But at $100 USD, it’s not really a bad value considering the capabilities it offers. What we wish for though is a CompactFlash version, since devices like this might be more useful to digital SLR shooters.
