Default mirror lock-up d100

I have a dust spot on the ccd(d100)
The manual says to select the mirror
lock-up from the menu. But when I
try to arrow the cursor to that option
the cursor jumps over that selection.
I am not using the ac adapter. Is that
the problem? If so what do you do if
your out in the field?

Hi Mike,

Well, this is certainly NOT recommended as a general cleaning rule, but you can do this:

1) Set your exposure to the max (30sec)
2) While your lens is on, take a pic
3) Take off the lens
4) Clean CCD before the 30sec has expired

This is for emergencies, but it can do the job. Of course, be sure you are in a setting where more dust can't get in.

Default Mirror lock-up

Thanks for the help. I contacted Nikon USA
and the reply was that the ac adapter did
need to be used in order to execute that
option. So this would be a problem if you
are out on location without access to an
ac outlet. I also don't understand why
Nikon didn't include the ac adapter with
the camera. By the way were you worried when you tried to remove the lens in the middle of an exposure for the first time, or
did you know that would work?

Hi Mike,

Well, hee hee hee. I took a chance, and yes, I was a little worried about locking up the D100. I heard while chatting online with other people a while ago that a person could do this, but it was not recommended unless it was a dire emergency. I had a few particles on my CCD, and I don't have the AC adapter, so that's what I did. The particles are gone, and I'm happy. Now, I just need to take of that one pesky particle in my AF-S 80-200. I'll be sending in that to Nikon. They can deal with it.

I totally agree about the AC adapter thing. Nikon should have included it with their "kit". They get a big frown from me on that one. I could see if the AC adapter was optional, but since everyone will, at some time, need to clean their CCD, an AC adapter is a necessity, not an optional accessory.

Over at the Nikonians board, this same method was suggested. Keep this in mind, the CCD is charged when you use this method and being charged can attract more dust. The concensus was to use the AC adapter.
