Together with two new cameras, Panasonic DMC-GX8 and Panasonic DMC-FZ300, Panasonic has announced that two new lenses, aimed at the Micro Four Thirds system, are under construction - Panasonic Leica DG 100-400mm f/4.0-6.3 ASPH Power OIS and Panasonic Lumix G 25mm f/1.7 ASPH. Aside from these innovations, Panasonic introduces a new technology into its cameras with the 4K video support, labeled Post Focus, which represents a mode in which the subject is focused after the image has been captured (focus-after-capture mode).
The Panasonic Leica DG 100-400mm f/4.0-6.3 ASPH Power OIS is a telephoto zoom lens whose equivalent focal length is 200-800mm. Developed in accordance with Leica's standards, this lens brings exceptional optical performance. Like the new GX8 and FZ300, the Leica DG 100-400mm f/4.0-6.3 ASPH Power OIS features the advanced DFD (Depth From Defocus) technology and brings high speed and accuracy when it comes to the exchange of the digital signal with high-speed Lumix G cameras at 240 fps. It is equipped with the POWER OIS (Optical Image Stabilizer), which delivers crisp, crystal clear images. With its compact dimensions and low weight, bearing in mind the telephoto category that it belongs to, this zoom lens enables handheld telephoto shooting without using a tripod, and it is also sealed, which makes it dustproof and resistant to poor weather conditions.
On the other hand, the Panasonic Lumix G 25mm f/1.7 ASPH is a fixed prime lens (equivalent: 50mm) with a very wide aperture - f/1.7. Its focus distance offers almost the same angle of view and sense of perspective like human eyes, which means that while shooting, e.g. portraits or scenery, you can catch the same angle as the one that you see with the naked eye. This lens, too, boasts the new DFD technology and a high-speed exchange of information with fast Lumix G cameras. In contrast to the said telephoto lens, the Lumix G 25mm f/1.7 does not feature image stabilization and is not sealed either.
As for the revolutionary Post Focus technology, thanks to the 4K video mode and the new DFD (Depth From Defocus) technology, it will enable users to select a focus point after an image has been captured. This function represents a further evolution of the 4K Photo technology and its goal is to prevent out-of-focus errors, as well as to additionally stimulate overall creativity. The Post Focus operates in such a way that fast and ultra-accurate focus of the DFD technology is shifted during a 30 fps burst of 4K footage, which means that shutters will have to be quicker so that there would not be blur during the burst (unless the lens stops 30 times a second for each burst exposure, which is hardly likely). While playing back the captured footage, with a simple touch of the LCD screen, the user can 'set' focus on a particular point, and the camera will extract a still image with the specified plane of focus, regardless of the fact where the original focus area was. This means that users can lay stress on different details within one and the same image by changing the subject with a simple shift of the focus position.
The exact date when the announced lenses Panasonic Leica DG 100-400mm f/4.0-6.3 ASPH Power OIS and Panasonic Lumix G 25mm f/1.7 ASPH will be launched, as well as their prices are yet to be stated. As far as the Post Focus technology is concerned, according to the company, it will be introduced in the form of a firmware update at the end of the current year, and it will be aimed primarily at the new Panasonic DMC-GX8 and Panasonic DMC-FZ300, as well as "some other models".
