5 of the best iPhone camera accessories

Olloclip

£55, amazon.co.uk
The iPhone 4 and 4S already have great video sensors – their only weakness is the small lens. Olloclip opens up the iPhone's eye with three lenses: macro for extreme close-ups, wide-angle for packing more onto the screen in a small room, and fish-eye for that warped effect that makes even boring video more interesting. It’s not cheap but it’s solidly made and the whole thing fits in your pocket, or worn as a monocle, if that’s your directorial quirk.
