In July, Panasonic revealed plans to launch a feature it calls Post Focus for select camera models via a firmware update. Panasonic today announced that firmware update will be available via the Lumix Global website next Wednesday, November 25 at 01:00 GMT. The Panasonic Lumix DMC-GX8, DMC-G7, and DMC-FZ300 will be supported.

The feature, simply called Post Focus, utilizes Panasonic's Depth from Defocus technology to capture 4K-resolution video at 30fps while shifting focus through the frame. Once the capture is completed, photographers can use Post Focus to specify the desired focus point, and the camera will extract the still frame with the corresponding plane of focus. The video above shows the feature in action, and demonstrates that focus peaking can be used after capture to help determine the best point of focus for macro shots.

Panasonic Frees Photographer’s Creativity with New 'Post Focus' Technology 

LUMIX DMC-GX8, DMC-G7 and DMC-FZ330 enable any area of a photograph to be in-focus after shooting  

Panasonic is encouraging photographers to shoot first and focus later with a new technological function called ‘Post Focus’.  After taking a picture, the function enables photographers to select whichever part of the image they want to be in-focus with an easy one touch operation. Developed with Panasonic’s existing 4K Photo technology, Post Focus not only prevents out-of-focus misshots but also offers greater creative freedom, and is now available via a firmware update for the LUMIX DMC-GX8, DMC-G7 and DMC-FZ330. 

Post Focus has been made possible by combining the high-speed, high-precision DFD (Depth from Defocus) auto focus technology and Panasonic’s 4K technology, made possible by the Venus Engine. Burst images in 4K resolution (3840 x 2160 pixels) are shot at 30 fps while detecting up to 49 areas of a frame for focus points at different depths of field. 

Operation of the Post Focus function is straightforward and easy.  Turn on post focus, compose and take your picture. Then, while reviewing the images simply touch the area you want the focus to be and a new image with the selected focus area will be produced as a separate photo. 

In addition, this function can be used for creative purposes in different types of photography such as portrait, landscape and especially macro, where the optimal control is needed. Focus peaking, 5x magnified zoom and other fine adjustment settings can be used for even greater focus control. Several different impressions can be taken out of one picture by changing the focus and defocus within the image to select the desired subject. This assures that the photographer can select the best shot instead of out-of- focus misshots. 

The Post Focus firmware update will be available at 01:00 GMT on 25th November, 2015 on the LUMIX Global site (http://panasonic.net/avc/lumix/) for the LUMIX DMC-GX8, DMC-G7 and DMC-FZ330.
