But it what about capture? This is where Olloclip comes in. It's a plastic cover with two small lens attached. The cover is placed over the iPhone lens to give a wide angle view. Turn the cover around and the other lens comes to play and you've got a fish eye. But here's the really clever thing. Unscrew the lens and you've got a x10 macro lens. The other is a x15. This allows for a ridiculous close up view of your chosen subject. Here for example is a common ladybird found in a common garden in the south east.
I'm not wildlife photographer, but the combination of the iPhone + Olloclip makes for some compelling images.
