Sony has released a free firmware update for its NEX-3 and NEX-5 interchangeable lens cameras that allows you to shoot in 3D.

There's no detailed specifics about how the 3D is actually captured, but the electronic giant states that after the download to version 02 firmware, you'll be able to activate the 3D mode by "pressing the shutter button and sweeping the camera from one side to the other".

Sony says that this will shoot a high-speed burst of frames, that the camera combines to create a 3D panoramic photo that you can view using your 3D TV. Obviously Sony recommends its Bravia 3D models, although it should work with any 3D television.

Version 02 firmware also improves the 2D panorama sweep mode, as well as decreasing battery drain and adds a quicker startup in dimly lit places. So you may as well get the update even if you're not interested in the 3D functionality. 

Update via the Sony Europe website, and when you have, let us know how you got on. Is it Avatar 3D, or free poster in The Sun 3D?
