Hi,

I've had my camera since Christmas and now I'm interested in purchasing an additional lens. I am torn between the Sigma 70-300mm F4-5.6 DG Macro AF lens and the Tamron AF 70-300mm f/4-5.6 Di LD Macro lens.

So I guess I'm seeking advice, opinions.. anything really to sway me in either direction or a new direction completely.

I mostly take pictures of my twins and of friends at dog shows while they are doing agility or dog racing. Wish I had a faster camera with the racing.

Thanks,
carol
