Looking for a really cool way to capture photos for sharing? Yes, there are lots of great photo filters apps for the iPhone. But, if you want your iPhone 4 photos to look a different from the rest of the crowd, take a look at this pair of hardware accessories (Note: I have not tried these items myself yet).
Both the Wide & Macro and ($49.99) the 180-degree Fish-Eye ($59.99) lenses attach magnetically to the iPhone 4. The Wide & Macro lens is, as the name implies, a dual function accessory. Its 90-100 degree field angle view lets you capture a wider view than is normally possible without stitching multiple photos together. Its macro function has a 4x magnification to get great ultra-close shots from your iPhone. The 180-degree Fish-Eye lens can capture nearly everything visible in front of you or to create distortion effects.
