As all the others have said, 'You most likely bought the best camera possible in getting the D700.'
I have owned my D700 for a number of years now and will not ever get rid of it. I also own a D300s, a D200 and a safe full of other Nikon SLR equipment. You can use all of your AIS lens on the D700 with manual focus. The D700 has the left/right arrows in the view finder with the green dot to tell you when you have obtained manual focus. Works great!
This past year I finally took the plunge and bought a D800. How did that work out? The large files are slow to download. Focus has to be right on or else the result is disappointing.
So what is the outcome? I find that I use the D700 95% of the time and the D800 just sits in the safe.
Regarding shooting RAW...... I only shoot NEF files. I then do the quick edit process using Capture NX. Doing this allows you to adjust the shots in case your light or exposure is off and this is NON DESTRUCTIVE EDITINBG. You always have the original file and will not lose information like you do shooting in JPEG or TIFF mode.
If I need to make a JPEG or TIFF photo it is quickly and easily done in Capture NX. The original NEF file does not degrade.
Capture NX costs like what.... $140?, so it is far cheaper than other edit software and it is a Nikon product and directly handles Nikon NEF files.
I urge you to try shooting NEF shots and try out the Capture NX software. It fits like a glove with a D700. Perry
