Today Panasonic officially announced the previously rumored firmware update with Post Focus functionality for GX8, G7 and FZ300 cameras:
Available with the latest free firmware download*, Post Focus allows you to take a photo and then choose your focal point later. With Post Focus, you can shoot with confidence knowing that you can always change the focal point if your photo was out of focus.
*Post Focus will be available on DMC-GX8, DMC-G7 and DMC-FZ300 by updating the firmware to version 2.0. Customers can download the upgrade from 26th November (GMT/CET 1:00 a.m. on November 25) at the LUMIX Global Customer Support Site.
