I'm seriously debating whether or not this upgrade is worth it. I currently own the following: D300 (Less then 2 weeks old, can still return) 12-24 Nikkor 24-70 Nikkor 105mm VR So to upgrade, its going to cost me $1300 plus the 12-24 will eventually need to be replaced either with a 18mm prime or a 14-24. So with that said, how many of you currently own a D300 and are pondering whether or not you will jump on the D700 band wagon? I guess the immediate benefits are: 1. Going super wide (but I kinda already have this, although DX is limited to approximately a 20mm FOV. 2. Better DoF control, smaller apertures with less worrying about diffraction, or larger apertures with shallower DoF. 3. Amazingly High ISO Would like to hear what everyone else is thinking.
