There's nothing worse than taking what feels like a great photo, then opening it later to discover it's out of focus. The Lytro Illum solves that problem by taking photos that you can focus and re-focus even after you've taken them.
The Illum is a light-field camera, allowing you to adjust focus, perspective and depth of field in an image you've already snapped. It works by absorbing and recording all the information that comes through the lens, then creating pictures that can be altered later by simply tapping on the spot you want to be pin-sharp and in focus.
Although Lytro was first to make a camera that changes focus, you can now do it in phones such as the-- check out -- which is a real blow to Lytro's prospects in the consumer market.
The firstwas a small block-shaped thing that looked nothing like a camera as we know it. The Illum looks more like a traditional camera, complete with a much bigger screen and a more familiar grip.
The original Lytro had a fixed lens, while the Illum adds an 8x zoom. It has a fixed f/2.0 aperture.
Lytro's new Illum goes on sale in the US in July and costs $1,599 (£950). If you get in early and buy one before 15 July, you get $100 knocked off a special engraved version of the camera. The company hasn't yet announced pricing or availability in the rest of the world.
