This is from the Olympus press release earlier this month.
“With the introduction of new firmware Version 3.0, the weather-resistant camera is now capable of an impressive maximum 9 fps in the C-AF sequential shooting mode when using a Four Thirds® or Micro Four Thirds® lens, improving the ability to capture moving subjects.
The newest firmware upgrade features an enhanced algorithm for phase-detection, raising the former C-AF sequential shooting speed of 6.5 fps to a maximum high speed of 9 fps. With this update, AF tracking performance is improved when using continuous-AF (C-AF) Sequential H mode. When set to C-AF, 37-point on-chip phase detection AF is used. Now, when capturing a quick-moving subject, photographers never need to miss the shot. A maximum 10 fps remains available when set to single-AF (S-AF) Sequential H mode.
The update also adds support for the latest Version 2.5 of the Olympus Image Share Android® and iOS® app. Users can now select Movie as a shooting mode, and record movies while viewing the Live View screen on a smartphone.”
