yep, all it does is change the 2-4 second test mode to 8 -10 seconds, 330k is supposed to give around 15 seconds.You should do this swap even if you think 2-4 second delay is enough, some of the cameras will require a longer shutter press than 2-4 sec to make camera fire after it sits awhile
Makes no change to the auto mode, it is a 70 -90 second delay, but can be retriggered and time starts over, cam could freeze if held for to long( 3 minute). unless you use the olympus infinity jr. I don't think the ywill freeze, even if you hold it for 5 minutes.
(I think) TMkarren knows more about this camera if he's kicking around??
