At the moment, I have the 24-70 2.8 and the 50 1.4G. I'd really like a little more zoom for a good portrait lens, and was thinking a macro would be nice too. So, i've been eyeing the 105 2.8G with macro, and was wondering if anyone out there has it, and would love to know what you think. Or any other suggestions on what to complement my other two lenses with? I can't afford the 70-200 at the moment.
