Earlier this year Panasonic announced it was working on a 'Post Focus' facility which would enable photographers to select the parts of the image they want to be in-focus after they've taken the shot. They intended it to be ready bu the end of the year.

They have been good to their word as the technology is now available for some Panasonic camera owners via a firmware update.

This clever firmware update is available for the Lumix DMC-GX8, DMC-G7 and DMC-FZ330 cameras.
