So, to match or beat an APS-C DoF achieved optically, you'd have to digitally crop the image out of FF, right?

The only confusion there is about you not being able to differentiate between digital cropping (FF file) versus optical results out of APS-C.

What's the difference between a) only collecting the light that falls on middle of the frame ("optical" crop produced by APS-C sensor) and b) collecting the light from the entire frame and using the pixels that are in the middle of the frame ("digital" crop of the FF sensor)? Except that in the second case you have the choice to use the extra image area if you desire.
