Ok, so i have an opportunity to spend some cash. Its a toss up between the Nikon D3s or the Nikon 200mm f2 lens. I currently have a D700 with a series of decent lenses(14-24mm,24-70mm,70-200mm) and an 85mm 1.4d. Im dying to get the D3s for its low light capability,speed and durability, but at the same time ive been wanting the 200mm f2, hmmmmmm. let me know what you would go with in my situation.
