It's a time-proven and once the media's go-to camera (along with Canons) — heavy, clunky, industrial-looking, robust and very business-like, all the qualities that appealed to me moving on from an Olympus OM10.
I lost my entire Nikon F3 and MD4 motordrive with 24mm lens in 1986 when I was hanging over the edge of a cruise boat on Tasmania's Gordon River. Then another recreational boat ripped past creating a huge wake that rocked the boat violently and had me lose my balance, falling into the water (others fell about on the deck) — Nikon and all. All...gone. It took me years to recover from the shock of losing a camera like that, and it's probably still resting at the bottom of that brutally cold, tanin-stained river in 2m of soft clay...
BTW, don't ever sell of 35mm gear just because you've moved up to medium format — tempting as it is, it's not sensible. 35mm still and always will have its place for odd-jobs.
