Joe,

When I put a 1 gb card in set to Raw PEF, it shows 61 images
available.  I shot a session that way and the card ran out of space
after 92 images were actually shot.  I'm sure some of the issue is the
amount of compression for the embedded jpg takes.  So the available
count is a guess.

No idea why the other mode changes things - only idea might be the
algorithm for figuring out that compression takes into account higher
ISO (noise doesn't compress as well).
