Hey I am new to this forum. I am currently doing an art foundation course and have only recently got into photography. I only have a small digital camera, so for my work I tend to use my mum's Canon Powershot S5 IS, as she never uses it. I was wondering if it was worth getting an upgrade for myself? I was tihnking of getting the 400D, but am usnure if this will be any better than the camera I am using now, and if it will be worth spending so much money on it. So should I stick with the S5 IS or get a new one? cheers for any help (in advance)
