...and this is exactly what I was talking about when I mentioned this more recent obsession with shooting everything at f/1.2 on FF cameras. I mean no offense here, this is just my opinion since you posted the two for comparison. That first example is ruined on the FF shot IMO because her hair, shoulders and most everything below her face is out of focus. It doesn't look professional IMO, it looks like someone who picked up an f/1.2 lens and went crazy shooting everything wide open because they could rather than thinking about if they should. No parts of your subject should be blurry, it looks amateur IMO. The shot below it on the APS-C sensor is much nicer and the background is plenty out of focus. The shots below it are better but again, look at her hair in the FF shot, its fuzzy and doesn't look good and her outfit goes out of focus. Any model I shot would not be happy with that and neither would a client if they were paying me to shoot an outfit. The APS-C shot below it, her hair and her entire outfit is sharp, in focus and looks great. In both instances, give me the APS-C shots every day of the week.
As a side note, I find the hair flyaways on top of her head in the first pics much more distracting then seeing a tiny bit more of the background in the APS-C shot. Those are easy to take out in post
So what you're saying is, despite your previous claims, FF systems have shallower DOF. I'm glad to see you've accepted reality.
