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.

Rory - the 70-200 f4 L doesn't have IS... that being said IS will do nothing for your aquarium shots as it compensates for camera shake not subject movement. Same goes for nature shots. IS is AWESOME when you are shooting a static subject at 200 mm and want to hand hold using a shutter speed of less than 1/200. No matter what, get a tripod, I recommend a Monfrotto 055 with a ball or grip head. Don't waste your money on a cheaper one, these ones fold and splay into any configuration you can imagine and pack nicely.

I went with the 580EX and 430EX flashes. Again on the expensive side, but ETTL II works superbly and the through the lens communication totally takes the guesswork out of flash photography. If you get a 3rd party flash, Sigma is the only one worth it's salt, the rest are junk... ask away, anything I can do to help & I will.... I read up for a month before I bought and had the added experience of buying a sub par system before that to know what I really wanted.
