Will continue to improve the focus but not sure to add phase AF. Panasonic said that the full frame is the same as the M4/3

Recently, in an interview with dpreview, Panasonic once again stated that in addition to continuing to develop full-frame systems, Panasonic will not stop the development of the M43 system. After all, the M43 system has obvious advantages, compactness, lightness, high mobility, and video performance. Excellent...and the two systems can adapt to a variety of different shooting scenes

As for the Panasonic focusing system that everyone is most concerned about (currently using DFD), Panasonic said that autofocus is a technology that is constantly improving. On LUMIX S5, the DFD algorithm has been improved and optimized through user needs and feedback. The post-market response is also good, but there is still room for improvement in focusing, such as improving processing power through new hardware, and improving focusing accuracy through new algorithm improvements. Not to mention, we look forward to our future autofocus Go ahead. What improvements will be made to future products? Panasonic said: There is no way to say in detail, but the GH series and S series have been well recognized in terms of functions/performance, such as S1H's unlimited recording and various shooting assistance functions. In the future, we will continue to listen to the needs of users. To improve and perfect, in the future, the new machine will receive the blessing of higher specification video capabilities, and will continue to improve the technology to create a camera that makes everyone more satisfied. via: camera beta
