Relative noob here with a normal monitor balanced the best i can. In response to the initial video, I couldn't really tell any difference in skin tones. The only difference I noticed on close second inspection was that the blacks on the Alexa were very slightly less black. I guessed straight away when I saw camera X that it was the Sony because of the sharpness, which was confirmed when I saw the softer image of camera Y. I think the Alexa looked more movie like because of this, so I think the f55 would be more suited to documentaries or product commercials. If used for narrative, perhaps a very slight blur could be added to the F55.
