Yep, pretty stupid all in all.
I keep my D600 and lenses in a Lowepro Slingshot 202 AW. Great bag by the way and offers ample protection under normal circumstances.
Anyway, in this case the Lowepro was on a shelf and I had zipped open the bag to get the D600 with attached Nikkor 18-35mm out. Somehow, I really don't know why, I decided to get the whole bag out instead...
...of course () I forgot to zip up the bag first. So, while the bag was still in my hands and tilted downwards the camera and 18-35mm dropped out (too quick to catch) and approximately 1.2 kilos was on its way to the carpeted ground.
I was a bit stunned, so cursed first, put the bag down and picked the camera up. I think the first point of contact was the edge below the screen and/or underside. The outside of the camera looked good, the carpet must have helped with that and everything was still attached (lens) and inside (battery).
So, I turned the camera on and pushed the shutter button. It seemed to focus, but slow and it didn't want to take a photo.
Long story short: the lens was fine, as the camera probably took the main hit but the mirror wouldn't go fully up anymore. Something must have shifted internally. In manual the camera still worked sort off, but it only produced half (normal) format photos, the rest was greyish, as it was obstructed by the mirror.
That was Sunday. On Monday I brought the camera in to the Nikon repair centre (15 minutes drive from my house) and they said I would probably hear from them in a week's time.
But, yesterday (Wednesday) it was already ready to be picked up. Mirror repaired, focus re-aligned and sensor cleaned. All for free.
After testing it at home I felt ok with it. All lenses are working normally and photos look fine.
This was great service and fast. I always liked Nikon, but am aware of the many, many things they could be handling better.
Still, this is the kind of thing that would keep me hooked on a brand I feel.
Now all I have to do is remember that the bag should stay closed when I take it off the shelf.
