Hey everyone, I currently have a Nikon d5000 and am starting to upgrade my equipement. I decided to start off with the purchase of a new lens, i do alot of portrait and show photography. Now my favorite lens is the 55-200 kit lens I own, so my first obvious choix is a brand new nikon 70-200 2.8 vr ii ( fits my budget!) I know many will say to opt for fullframe body, and upgrade this first.... am I going the wrong route? or is it a good idea to get my top glass first then upgrade to a new body ( even though the d5000 fits my needs) need your opinions!!!
