I am so torn right now- just thinking out loud here. I bought a D300 within the first days of them being available and I love the camera. I never really saw me going for the expense of a D3 so I was not too worried about collecting DX glass. Now with the D700 coming out I am rethinking everything. I really want to have the full frame ISO performance- and that is 99% of the motivation here. Lots of things running thru my head on this- so I decided to put it on paper and see where I am at. My Right-Now Set-Up Main Kit D300 w/ Grip | 10.5/2.8 | 50/1.4 | 150/2.8 Macro | 11-16/2.8 | 17-55/2.8 | 70-200VR Travel Kit D80 w/ Grip | 30/1.4 | 18-70 | 70-300VR Film Kit F100 | 35-70/2.8 | 180/2.8 My Kid Daughter's Kit D40 | 18-135 Soon to be For Sale? D40 | 10.5/2.8 Fisheye | 30/1.4 Sigma | 11-16/2.8 Tokina | 18-70 | 17-55/2.8 - Should sell for $3000 +/- New Purchases? D700 | Sigma 12-24 or 15-30? - About $3600 +/- My Maybe Add-A-D700 Set-Up Cameras D700 | D300 | F100 Lenses 50/1.4 | 150/2.8 Macro | 180/2.8 | Sigma 12-24 | 35-70/2.8 | 70-200VR My Kid Daughter's Kit D80 | 18-135 | 70-300VR So the whole shift would leave me with more camera- less glass- wondering if it is all worth it or if I should just preserve my DX kit and buy some FX stuff next year when I could afford both. I just keep thinking would I ever use a D300 + Sigma 30/1.4 combo if I had a D700 + 50/1.4 available? Pretty much the same thing with all the wide DX stuff- I am only keeping the D300 for the long end.
