Hi, Have upgraded to a D700 from DX camera previously. Need to buy new lens for D700 and mainly shoot weddings. I have the following prime lens 28mm, 50mm, 85mm and looking to eventually buy a 24-70mm and 70-200mm zoom as dont want to use DX zoom's. Due to expense was thinking of buying 1 lens now and another later in year. Which lens would be used more the 24-70 or 70-200mm? I was thinking of buying 24-70mm 2.8mm for D700 and then using D90 I have with 55-200mm DX lens. Or would I be better to use the prime lens I already have and then purchase 70-200mm 2.8? What do people think?
