Thanks HB-yeah $500 isn't pocket money when I'm having a tough time justifying $1200 for the 28-70 to my cheap and critical self.
Do you think the 28-70 would be a bad walk around lens due to it's weight?
Excuse the dumb question but is this full frame digital still fairly new? I was looking at the D700 last night and it appears to be about $2,500 discounted and the D3 variations range from about $5-7K. I would guess that if the full frame CMOS body is still new we will see those prices drop within 2 years?
I really appreaciate all the advice from everyone. Learning how to really use my DSLR is a goal that I am working one. I used to do a good amount of 35mm photography and then I got busy with other boring life things when the DSLR market took over and never learned to get the most out of my D70s.
If you did 35mm photography then you are used to a full-frame. A DX sensor is a cropped sensor. On Nikon it's a 1.5X crop factor and on a Canon it's usually a 1.6X crop factor. Take a 50mm lens for example. On a full-frame, it's 50mm (the focal length you get is identical to that of the lens). On a cropped (DX) sensor a 50mm is the equivalent of 75mm (50 X 1.5).
This is why you shouldn't use DX lenses on full-frame since they are designed for the cropped sensor. Buying the better glass upfront will benefit you in the long run.
Cropped sensors are bodies such as the D40, D40x, D60, D90, D5000, D3000, D200, D300, D300s, etc. Full-frame bodies are the D700, D3, D3s, D3x, etc. (In the Nikon line-up).
