I had to buy me a new remote release for the E-30, because this (semi-professional?) - Camera no longer has any connection to the Olympus RM-CB1 (such as the E-1, E-300 and E-3). Since it is known priced gold dust is stored in genuine Olympus accessories, I bought the Delamax remote release. He does his service without complaint, even a lot longer than the RM-CB1, and the little fiddly USB port will probably hold in my rare use for a long time.
