p.1 #6 · Do you lost any f/stop on a lens if shooting a crop sensor?
Yes, just to confirm and clarify: Exposures do not change going from full frame to crop, but depth of field at any given aperture and focal length will be a little greater on a crop sensor. Not by much, but something to note.

does 2.8 on crop really look like 4.0 on full?
i'm probably wrong, but to me it seemed like 40D+24L at 1.4 looked like 5D+50L at 2.8. that's 2 full stop of difference in dof.
i donno. maybe my eyes are messed up.
You're adding different focal lengths into the mix here. And giving the longer focal length to the bigger sensor. So in your example here the bokeh may well look like 2 stops different.
