p.1 #1 · Removing D800 Focus Screen?

There is a bit of junk behind one of my D800 focusing screen. Can the focusing screen be removed/released for me to blow it out? Searched the web and could not find an answer. Really would not want to send the camera to Nikon for this.

Yes, easily. However, please have s proper tool for lifting the tension wire holding the screen.
You could purchase one from KatzEye.

They are easily scratched. Be careful. You will know it when they are scratched because they look like dust bunnies through the viewfinder that never go away. I'd make sure replacements are available.

Release it, let it fall down and puff with a Rocket Blower behind it. Then lock it back up. May or may not work because the plastic has a pretty strong static attraction to dust. Don't take out if you don't have to.

So I had a KatzEye tool for my D700 and it worked in releasing the wire. Blow it out but the spot still remains. Took out the screen and the spot is not on the screen and it's not on the mirror above either. Could it be behind the upper mirror?

Looks like I may have to send it in after all.

Are you sure it isn't on the inside of the eyepiece?

Seriously? For a little dust in the eyepiece? If it's not on the sensor or the lens, it doesn't affect the image, so my suggestion would be to learn to live with it. I certainly wouldn't advise disassembling a camera for a little dust in the viewfinder, nor have I myself over the years. You're more likely to end up with more stuff inside (even if done by Nikon service).

I second James R, take out the eyepiece and blow that area clean. Then redo the focus screen. What always happened to me, as I was saying above, is the dust you blew off would zap back onto the screen because of the static charge when you were putting it back in...

I am thinking of selling this camera so want to make sure everything is ok.

It's not behind the eyepiece. I checked that first.

Understood, but you may end up spending more to clean the bit of dirt than you would lose by discounting the price a little bit to reflect its (cosmetic) condition. If you think Nikon will clean this without charge, then you'll only be out shipping, but I'm not sure whether the warranty would cover this service. At this point, you may as well call Nikon and ask them.
