Hi all, I've decided to step up to dslr, the Nikon d60. I'm looking for an all-in-one lens for it, and since I'm totally new to the whole photography business, I want to keep the price as reasonable as possible. I'm thinking of getting the Sigma 28-70mm F2.8-4 DG and would likely make a trip down to the US and A to get it, since the price there is much cheaper (I believe it's around 100USD down there?) while in Canada it's 200CAN. I think I'll just be shooting normal pictures (like a point and shoot) not macro or tele or anything, so does this lens suit my needs? Any suggestion is greatly appreciated, as I am totally new to photography and would really like to learn more.
