I've decided to make the jump from P&S camera to the next more expensive level. I have an Oly PEN EPL2, the stock 14-40 lens and the 9-14 wide lens. I do not yet have the Zen port. Though initial testing I think i will be happy for now shooting 9mm through the stock flat port. Yes there is distortion and chromatic aberations, but its not noticeable in Facebook sized pics, so I will live with that for now until I can get a port sent over to Thailand. I am however, looking to add some strobes, this will be my first time using an external strobe underwater, or above water since my Pentax K1000 days. For underwater, is it that much harder to learn shooting two strobes? Should I start with one strobe first and learn with that then add the second later, or plop the cash down upfront? I'm looking between a S2000 and YS01. I would guess i would shoot a roughly even mix of wide and macro.
