The combination of the FS5, the RAW upgrade and the Shogun Inferno allows high quality 50 fps recording at 4K. This sequence was shot at our local beach late on a winter afternoon, with strong sunlight, and in a windy spot.
We used the Sony PZ 18-110mm f/4 G OSS lens. Shot in Slog3 Cine, with LUTs applied. One interesting point is that RAW reads data direct from the sensor and so no lens correction is applied. As a result you can see the horizon distorts just a little, (e.g. at 17s), something which disappears when not using RAW. But then you cannot get the highest quality from the sensor!
