The C220 (the one that I have, at leas) has etched lines that I use, but not a moving bar like the C33. You look at the focusing scale to see the recommended bellows exposure compensation, and then use the etched lines that correspond with certain amounts of EC.
P.S. Just checked the C33. It is there...and now I remember it. I forgot about it, as I have used the C220 as of late, and have only really used the 80 on the C33. I generally have left the 80 on the C33 and put other FLs on the C220.
