I have a D700 and an old Questar 700 lens. I find when I try to use the non cpu lens setup that my options go from 600mm to 800mm and there seems to be no way to set it at 700mm. The aperture sets OK. I seem to be able to focus manually OK, but am wondering it it make a difference in how the camera handles the lens.

The focal length and maximum aperture settings for a manual lens are used by the matrix metering in the Program or Shutter-priority exposure mode set, otherwise the settings are mostly notational.
Either value, 600mm or 800mm, would suffice, only the EXIF data for focal length would be a bit off.
