The manual for both the E-300 and the E-330 state that sequential shooting is possible only in JPG format. However, by chance I discovered that my E-330 can do it in RAW, so (for this forum) I tried it with my E-300 as well. No problem. I don't know if they always had this capability or if they gained it after firmware updates, because I have updated both as new releases have come out (on the Olympusamerica site). These updates always seem to have some unexpected benefits. It would be nice to know just what they are, mind you, as new menu items become available without explanation. Still, I give Olympus credit for their quite frequent updates.
