It is hard to imagine the F3 without associating it with its dedicated companion motor drive, the MD-4. Nikon has designed some very good motor drives for their professional camera bodies since the days for their rangefinder model in 1957 and I don't doubt they can produce first-class motor drives with three decades of experience behind them. But the MD-4 was a marvel and deserves my respect for all those brilliant brains behind the design and development team of the Nikon F3/MD-4. With a well-engineered camera body, a high-quality optic, and coupled with today's excellent film technology, it is difficult not to take good photographs.
