Hey all, I'm wanting to buy a high power zoom lens (i have a 18-70mm and a 50mm). I would like something that gives me the next level, e.g. 70-300mm. I was looking around on the Nikon site (canadian) and came across this lens: http://www.nikon.ca/products/af-zoom-70-300g/ Anyone use it? Like it? Hate it? Is there something better. BTW, I'm using a D70s. Thanks.
