My Nikon D3, now with over 22,000 shots taken suddenly started automatically changing shutter speed after every shot, though using different lenses.  I mean jumping to 1/5,000th or 1/60th second, well outside normal bracketing of exposures for intentionally set/reset 1/320th and f/11.  You would think I know my own camera, by now.  I DID NOT PLAY WITH BRACKETING -and- IT DID NOT NEED TO BE RESET.  So, eliminate that response. As soon as I returned home, I installed a freshly recalibrated and recharged battery.  I cleaned the contacts, in the camera and lenses. I reformatted the CF Card.  I Reset the shooting menu.  I Reset custom settings.  I upgraded Firmware from 2.02 to 2.03.  Nothing seemed to remedy the situation.  Finally, after many tries and no joy, I depressed the ISO and W/B buttons, simultaneously, for 2 seconds.  I did that a couple times.  I have gone out to take 19 photos and now everything seems to be normal(?).  Is the Nikon D3 ever really normal???  Question I have is WHY ON EARTH would the D3 develop a mind of its own and set Shutter Speed randomly, after every shot?  Oh well.  I bought and paid $5,000 for the camera, when new, back in 2008, putting my Nikon F4S on the shelf.  Damned sorry I spent the money for this iteration of Nikon professional digital camera.  I should have kept my money in my pocket.  If I didn't own about $75,000 worth of Nikon pro lenses and accessories, I would pitch the D3 over the fence!  The Nikon F4S/E was the best camera Nikon EVER produced.  A real Photographer's camera.  My guess, Nikon may finally get it right when the D6 is introduced to the market.  Maybe.
