shaky

Hi, I need some help deciding between a wide angle lens (Olympus 9-18mm) and a fisheye (Lumix 8mm) for my Olympus EPL 2. I have been thinking about this for a couple of weeks and am changing my mind almost every day.

This is what I would like to use it for: My next trip will hopefully be to Sipadan (so mostly turtles, reef sharks, etc) but I am also hoping that I'll be able to do the shark dive in Fiji or even humpbacks in Tonga at some point. In addition I would like to give close up wide angle a shot as well. I would be nice if I could also use the lens for topside photography, but guess the fisheye optic is a bit limiting here (though i have seen a few really cool fisheye images recently).

I read somewhere that the fisheye lens is a lot harder to use. Is that true?

Any help making that decision would be most appreciated....

Hi, I am a complete newbie and am thinking about getting the EPL-2 and the Olympus housing. What sort of macro lense would you recommend? Backscatter has a set which includes the Olympus macro conversion lens and 67mm Macro adapter. Is that a good setup for macro, or would you recommend something else?
