Abelcine have tested the dynamic range of the production model of the FS100 and have found some nice improvements over the pre-production model. Roughly 11.5 stop now.
The F3 S-Log upgrade, part number CBK-RGB01, is available for purchase now. With this upgrade, and an external HD-SDI recorder, well will start to see some beautiful footage showing the true capability of the F3 soon.
Sony have released the free firmware update for the F3. This update enables quite a few things, including HD-SDI and HDMI simultaneously, as well as Planning Metadata and more Dual-Link modes. Upgrading my F3 now.
