I sold my reefmaster after my last dive trip because it didn't have the close up capabilities I needed. I was considering the oly 5050 but I'm not so sure I want to spend so much cash on something I won't use that often. Please give me some feedback on the a70. It looks like the macro mode on it will cover my needs. Can I change modes from macro to normal in the middle of a dive? Most of the pics I take will be within probably 5 ft. Will the standard flash give me decent pics or will I need to have an external flash? Basically the onlly place I take UW pics is cozumel. So, based on what I've said, let me know the results. Shutter lag is my only real concern. Thanks in advance, Greg
