Welcome aboard Graham !
Was very happy with the camera at Mondello, loaded off around 740 on the day and uploaded around 630 and that was just on the one CF card (1GB)
Used mostly P and M modes all day and never higher than 400 ISO
1/250th of a second, f5.6 @ 170mm ISO400
1/500th of a second, f8.0 @ 290mm ISO200
1/125th of a second, f7.1 @ 130mm, ISO100
