Speaking of Abdel Ibrahim, I’ve been meaning to link to his detailed comparison of the Olloclip and iPro Lens camera attachments for the iPhone 4 and 4S:
There’s no question that the iPro Lens takes better pictures, and
its handle gives it a leg up on videos, too. The Olloclip, on the
other hand, comes in a much smaller, more convenient package that
outshined the iPro when I was on the go.
