How would some of Nikon's older, less expensive (on the used market) lenses perform on the D750? I can afford a refurbished body, but that will wipe out any funds for a new Nikon lens. KEH has several moderately priced, auto-focusing, older mid-range zooms listed for less than $200. Are the older lenses at least a half-way decent match for the newer bodies? Any recommendations for a used, inexpensive, mid-range zoom on the D750?
