My friends D800 Exploded
Apr 6, 2012

Someone please fill my in on what happened. We did not notice any noise just a dark spot on the view finder and check out the damage. This camera was S/N30004XX (xx is the final two numbers)

Did it come like this? A few users have reported these random spots in their D800's already.

Or did it literally explode when your were shooting?

That's Sony sensors for you!

No, I think we got around 1500 clicks on it. I noticed the dark spot on the view finder. It still works and pictures still look good. Not sure what failed on it. I mailed it back to nikon. They told me 7-10 days.

Early adoption woes. Warranty should cover this, no?

Stress fracture?
In reply to Mssimo, Apr 7, 2012

Looks like a stress fracture in the viewfinder screen. Could have been some foreign object wedged between the frame and the screen. Not sure what the shiny spill is next to the screen.

I think that is melted plastic. Seems like the focus screen and mirror also melted.

A short burning some of the metal coating?
In reply to Mssimo, Apr 7, 2012

Looks to me like the pitted metal and missing black coating got vaporized and that's the dark comet shadow on the focusing screen.

Wow. You need to ask a new one.

I fear there will be quality issues for early adopters as Nikon was not ready to launch this camera and the high number of orders is going to put stress on their production lines.

Component Infant Mortality

Manufacturers attempt to screen out components with hidden defects before shipping product, but inevitably, a few manage to get out the door.

This could have been a capacitor, such as a bypass capacitor connected across the power supply, or perhaps an active component, which failed dramatically. Sometimes assembly errors such as installing a polarized capacitor with the wrong orientation, or an incorrect part type, will not cause immediate failures but then will produce a failure later in the field.

Looks like it came from a small board in the viewfinder area and partially impacted against the upper surface of the viewfinder screen as it moved downward at high speed.
It's a good example of the reasons why we want warranties on new gear.

I had one of the early D200's with the infamous "banding". It's a risk we take. Nikon will surely cover it, as they did back then.

Still a hassle.

Was your friend taking photos with the sun on the edge of the frame? I seem to remember a photo of a D200 that looked like this after sitting on a tripod for a few minutes with the sun shining in the lens. Or, could be a component failure as others suggested.

You can look above the viewscreen

At the center of the front (towards the lens) edge of the viewscreen, is a metal tab that you can pull forward to release the viewscreen, then you can see what's above it. Might be interesting.

Interesting theory, Marianne. You could be onto something.

If that's the case there should be something rattling inside the body, unless it got wedged somewhere.

Which lens was in use? Did it the mirror contact the back of the lens? Look there also, unless the damage is on the hinged side of the mirror.

Was your friend shooting into the sun or was the camera inadvertently aimed into the sun?
