Showing Steve-From-Work my new iPhone lens by http://www.olloclip.com/ and took this to show him the fish-eye lens ... And I liked it so much I discarded all the other photos I took today.
Loving the macro one as well ... that may well be tomorrow's shot.
Taken on iPhone5 using the Olloclip Fish-Eye lens and processed in Photo+, Snapseed.
I'm definitely getting me one of these olliclip things.
And yes, get the Olliclip. Apple Store on Regents Street has them.
