Another contender in the race to produce the world's smallest, lightest interchangeable-lens camera, Panasonic's Lumix DMC-GF3.
It's certainly one of the most pocket-friendly lens-swapping cameras so far, but at £500 with a 14-42mm lens, it's a bit pricey. US prices are a bit better (see below).
The 12-megapixel GF3 comes in a rounded aluminum chassis, with a 3-inch touchscreen and built-in pop-up flash. One cool feature is that you can focus and take a picture by tapping on the screen.
