This guy compares the FF and the regular 6k. Slightly disappointing as they seem to perform exactly the same? No way that's possible, right?
I am confused. To my eye, in all the videos that I have seen on the web so far, the BMCC 6K FF produces better quality images than all the prior BMCCs . If you ask me to do a blind test choosing between the two (FF vs s35 6K G2), I am sure I will perform with near 100% accuracy. In fact, at the beginning of this video, I spontaneously use my hands to block the info about which camera was which, just to have the chance to 'feel' the difference and to choose freely. And, in all times, I was correct: I prefer the one on the left (6K FF) than on the right (s35 6K G2).
I think that what Josh Sattin tested, when comparing the overexposed and underexposed images, was technically 'latitude' (image recovery), not 'dynamic range'. For dynamic range you have to do the kind of quantitative tests that the guys at CineD, Gerald Undone, and others do (you have to measure signal to noise ratios at the extreme stops).
The problem with comparing cameras with just a couple of basic static scenes is that you don't get the 'feeling' of the image. I consider much more informative to show 'real' scenes, side by side, hopefully as many different ones as you can (also including people and camera movements). This is the only way you can get a proper idea of the quality and character of an image, and I am surprised that few people are doing this in a time of abundant camera tests on YouTube (CVP, CineD, Gerald Undone, they don't do that either). Instead, all of them use charts and plastic artificial scenes that don't let you have a 'feeling' of the scene (this is not saying that you can't do the charts, they can be informative, but that you cannot jump into conclusions just by looking at those charts, you need real complex real scenes to judge properly; and they shouldn't last just a couple of seconds, the brain needs time to judge!). And you shouldn't judge this approach too subjective if you can guess which camera is which with more than 80% accuracy. Maybe you don't know why you prefer one over the other (it's difficult to put an experience into words), but if you can guess systematically and with good accuracy an image difference, this means you are pretty aware that there is a 'real' difference.
I appreciate all the excellent work Josh Sattin does to educate people about camera technologies and how to use them, but in this case I have to deeply disagree with his statement that the BMCC 6K FF produces basically identical images than the s35 6K G2. I think that the just too simple design of his test was not adequate to capture the real and significant differences between these two cameras in terms of image quality.
If an analysis contradicts most of the experiences of seeing real footage coming from the 6K FF (versus the s35 6K G2), well, good scientific practice tells you that you have to revise your testing, instead of concluding that they produce basically identical images.
