I have the 952AF/PEN and if I go manual it's a pretty powerful flash but in pttl mode it underexposes and if you need a lot of power in pttl it cannot give it for some reason. I know that it can't give 100% because of how pttl works but it looks like it can't match even the 50% power. i.e. where 50% would expose perfectly, in pttl mode it will underexpose by some 2 stops.
