As more photo applications enter the mobile app market and the camera capabilities of the iPhone improves, it's no wonder people are leaving their cameras behind in favour of their smart phones.

Black Design Associates has created a new concept that combines iPhone 4 photography with a Leica fixed lens rangefinder camera, which could be used as just a case but also enables optical zoom, shutter dials and flash.

Obviously it's still a just a concept but does look great, particularly if you're a bit of a photography fanatic.
