I'm curious to know what cameras and photography equipment you use for your pictures.

I use a Canon A-540 (6mp) with 3x optical zoom + 13x digital zoom, and macro setting. Sometimes macro isn't good enough so I use the manual focus (which lets me focus down to 2 cm!) which is great to show tiny details. I also use a tripod to stabilize my shots.
During the day I usually set the ISO speed to 80, but for darker shots I have it on 400-800 (which makes the pic quite grainy).

I am thinking of getting a macro lense for my camera. For those of you that use one, is it worth it?
