Maybe I missed it going through the manual, but I always thought a missing feature was being able to automatically set off all the shots in an auto-bracket without hitting the shutter release each time. Last night I was doing a bracket with a 2 sec delay and MLU. I had actually forgtten to activate the MLU. I pressed the shutter, got a beep, and 2 seconds later it fired off the sequence automatically. Might work on the other 1's - don't know.
