I’ve had the C300 up side by side with the F3 today. So far, remarkably similar performance, although the colorimetry is very different. One interesting observation is that the C300 sensor appears to be about 10% larger than the F3’s sensor. Certainly with the same lens I get a wider FoV from the C300. C-Log and S-Log look quite different. Another observation is that the F3 appears to be slightly more sensitive at any given ISO, maybe by over half a stop.
More to follow as I evaluate my test results.
