The iPhone 4 is a tremendous walkaround camera. I'm going to buy a Fuji X100 next year as a dedicated take with me everywhere camera, but until that arrives, the iPhone 4 is a lean mean alternative. It's HDR mode is very good - although I haven't used it much yet - and it's small size and the fact that it's a phone means it's always with you whenever a shot might appear. As a previous owner of the original iPhone and the 3G, I can tell you with confidence and experience that with the latest model the iPhone camera has really come of age.

These are some of my favourite images from the summer.
