you mean F5.6 on APS-C vs F8 FF? I thought subject distance plays a factor as well?
For the specific shot both the hands and the eyes needed to be in focus, luckily I shot at f8 for most of it, tried 5.6 to get a better ISO but forgot about DoF on a FF. I'm just used to what's in focus with a given f-stop and effective FL on aps-c cameras. It's my first time using a FF in a real shooting environment so I consider it a shakedown cruise, so to speak.

Yes, I suppose you could shoot at iso 100 and have all your photos black and then brighten them up four stops in post, but then you wouldn't have a clue if your focus was on and if your composition was correct and those are probably more important than noise and dynamic range in most photos anyway. As far as the depth of field thing, I don't understand the issue. If you stop down roughly one stop from where you shoot on APS-C you should have similar depth of field (assuming equivalent focal length and distance to subject).
thats' the thing with FF I wasn't prepared with. for similar DoF compared to APS-C you're stopped down a stop, but that means either shutter or ISO have to give. Just didn't have time to change the ISO in flight when sometimes I had to be at a minimum shutter to freeze motion, so being invariant is a big help when I'm one stop off. plus instincts kick in and I change back to the fstop I'd be on when I'm using a smaller sensor, with slightly embarrassing results.
