As long as I've been using the SP-350, it has locked out the built in flash for super-macro. This is a feature that is listed in the advanced manual because the lens blocks the flash at close distances. It has always worked fine with the external flash. Today I took the camera out for the first dive back in Monterey after my trip to Fiji and the strobes wouldn't fire in Super Macro. I tried the force flash button and the only choice was no flash. I reset the MyMode super macro setting and reset the flash for external only. Still nothing. I thought about using the reset button and starting from scratch with all new settings, but I'm a little worried this will screw up something else. Any ideas? Next step is to try it with my backup camera.
