Camera & Lense Recommendation

[TheReefGeek]

I am definately leaning more towards Canon now, especially with the vertical grip information.

Good info on the sigma, i'll let you know once I figure out what the heck I am ordering. (will be within the next week or two so I get it in time for my honeymoon)

What about flashes for canon? Do you have one you recommend? There is a knock off brand Sakor

They Canon EF 70-200mm F4 L USM, does this have image stabilization though? I will be doing mostly handheld photography, more than tripod.

My use of the camera is for aquarium pictures, and nature pictures primarily.
