Two new lenses and 'Post-Focus' technology on the way from Panasonic
Alongside two camera announcements, Panasonic has gone public with plans for a new post-focus feature and two more lenses for the Micro Four Thirds system. Confirming reports from earlier this week, 'Post Focus' will bring a focus-after-capture mode to certain Panasonic cameras with 4K video support.
Capture and re-focus
Enabled by 4K video capture and Panasonic's DFD (Depth From Defocus) technology, Post Focus will allow users to select a focus point for an image after capture. Unlike true light field capture, Post Focus works by shifting focus during a 30fps burst of 4K footage. As such, we'd expect it to have somewhat limited utility for moving subjects, and shutter speeds will likely have to be short enough in duration to not result in blur from the rack focusing during the burst (unless the lens stops 30 times a second for each burst exposure, which seems unlikely). In playback, the user can touch the LCD to 'set focus' on a particular point and the camera will extract a still image with the specified plane of focus.
A firmware update will be available for the newly-minted Panasonic Lumix GX8 and Lumix FZ300 'and some other models' in late 2015 to enable Post Focus, according to the manufacturer.
Leica DG 100-400mm F4-6.3 and Lumix G25mm F1.7 on the way
On the lens front, Panasonic disclosed that a Leica DG 100-400mm F4-6.3 telephoto zoom is under development. Covering an equivalent range of 200-800mm, it will include Power O.I.S. stabilization. The Lumix G 25mm F1.7 will offer a 50mm equivalent focal range and, like the 100-400mm, will support DFD and high-speed AF on compatible Panasonic bodies.
Panasonic LUMIX Announces New Technology
Two New Lenses and Post Focus Function
Newark, NJ (July 16, 2015) – Panasonic is proud to announce the development of two lenses and a new technological function called “Post Focus.”
Post Focus will enable users to select an “in-focus” area after shooting with a simple interface. This function has been developed as a further evolution of 4K Photo technology to prevent out-of-focus errors and offer additional creative freedom.
By combining high-speed, high-precision DFD (Depth From Defocus) auto focus technology and the 4K Photo burst images in 4K resolution are shot at 30 fps while shifting the lens to set focus on approx.50 areas (*TBC).
With the Post Focus function, the best image can be selected from the 4K burst images shot with different focus areas. Once the composition is fixed, you are free from the job of serious focusing. In addition, this function can be used for creative photography such as landscapes or portraits. Users can pull different impressions out of one picture by changing the subject to enhance it with focus. The operation of the Post Focus function is quite easy – just touch the point where you want to set focus while playing back the image, no matter where the original focus area is, and the image with different in-focus area will be produced as a separate photo.
Panasonic will introduce this Post Focus function via a firmware update for LUMIX GX8, LUMIX FZ300 and some other models in late 2015 and 2016 will study to integrate it into upcoming LUMIX digital cameras as well.

New LEICA DG 200-800mm (35mm Equiv.) Zoom Lens Under Development
Panasonic is developing the first LEICA DG 100-400mm / F4.0-6.3 telephoto zoom lens (35mm camera equivalent: 200-800mm) for the Micro Four Thirds system standard to expand the lineup of DSLM (Digital Single Lens Mirrorless) digital interchangeable lenses.
The LEICA DG lenses are designed and developed under the stringent quality standard certified by Leica that boast excellent optical performance. Four single focal length LEICA DG lenses have already introduced to the market and have been highly acclaimed by users worldwide.
The new telephoto zoom achieves exceptional imaging performance over the entire zoom range. It also features high speed digital signal exchange at 240 fps to comply with the high-speed, high-precision AF (Auto Focus) with DFD (Depth From Defocus) technology on LUMIX G cameras. Together with the POWER O.I.S.(Optical Image Stabilizer), it lets users to focus on the target quickly to capture crisp, clear images. In addition, the new lens is both light and small and is splash/dust-proof to withstand heavy field use. As the new telephoto zoom lens excels in size and weight, it enables handheld 800mm (35mm camera equivalent) telephoto shooting without using a tripod.
