I've never owned the 28-70 AFD Nikon.......one short range zoom I can really recommend is the 35-70mm 3.5 manual focus (same aperture throughout zoom range) it's incredibly good and also has a macro function at 70mm. I used it extensively when working as a pro., it's the only zoom I've owned that I can confidently claim matches the fixed focal lengths over the range. A truly stunning lens. (don't confuse this with the cheaper 3.3-4.5 lens over the same range, it's not in the same class.)
