Sony has announced an upcoming firmware update for its Alpha 7 and 7R full-frame mirrorless cameras. Due on March 19th, the update promises faster startup speeds, improved image quality (in what respect is not clear), a pair of new downloadable apps (Live View Grading and Smooth Reflection), and 'smoother' transitions in time-lapse mode. The firmware will also add support for Fast AF (Hybrid in the case of the A7) and the focus hold buttons on the 70-200 F4 FE lens.
