LightSnow Dev have released a hacked firmware update for the Olympus OMD EM-1 ...
The main feature of this release is, that is a bigger part of the sensor for the 1080p videos. This means that a resolution similar to 4k is read by the sensor and then downscaled to 1080p. You gain a lot of nice things like:
The Auto Focus in videos should be smoother.
Full Sensor read in video mode. No crop.
Better ISO performance in low light video situations
More Dynamic Range in video
This firmware is based on the official version 2.0.
This firmware is in development. The changes are sometimes only visible if you compare the firmware with he unhacked one side by side.
