I believe there is one good shore dive, full of Macro, I want to do that. I will use my 60mm for that.
Hey A1 I get that your camera is pretty massive for the first trip through the cave... why don't you take one of my spares? Fits in a pocket easy and if you see something you can pop off a shot or two....
My first trip through the cave I had it on video and just taped as I approached the entry and the light... fish brushing around my camera and cheeks... got some nice shots. I will have both cameras there anyway!
