sir, mirror lock function is currently not highlighted in my nikon d80. though it used to appear for lens cleaning purposes. it says that function is not available on current setting. i want to know what can i do to rectify? i tried that option for minimizing camera shake though i found later that it was not meant for the same. please guide me.

Is the lens off and the battery fully charged? Sorry for the simple question, but sometimes I forget about these things, and the setting can't be highlighted unless these conditions are met.

I don't have a D80, but on some Nikon DSLRs, the mirror lock function is only for sensor cleaning, not for taking pictures. And they require you to power the camera with the optional AC adapter/external power supply so that the battery won't run out in the middle of cleaning.

When I first got my D100, I put a fully charged battery in it and used the B shutter speed to raise the mirror for sensor cleaning. I spent like over 30 minutes to play around and to my surprise, I managed to drain the battery.

What Jason said, your battery needs to be fully charged or running off an AC power (apart from having a lens attached).

Shun is right. This camera will not allow mirror lock up for taking pictures. It is for sensor cleaning only.

Check your user's manual - page 125 of the English manual.

It says the battery must be over 50% charged and to remove the lens.

The removal of the lens may be due to that fact that it is supposed to be used for cleaning the sensor. I'll have to try it and see.

Your D80 has a exposure delay mode to minimize camera shake instead of mirror lock up which is used only for sensor cleaning. With the delayed exp delay mode setting selected, your shutter triggers a fraction of a second (0.4s) after the mirror has swung up and the vibration has died down. You can access this function via menu, custom, exp delay mode.

To access the mirror lock up (for sensor cleaning), ensure the battery is charged, remove the lens, in the Set Up menu (spanner) select 'Mirror lock-up' and highlight 'ON', then press the OK button - press the shutter button and the mirror will raise allowing access to the sensor; to lower the mirror, turn the camera off.

I have the D80, and it does not have the kind of mirror lock up you are thinking up. It's a "mirror up" function, for sensor cleaning as others above mentioned.

The mirror lock up function is on the WRENCH menu. In my camera it is highlighted BUT you have to remove the lens first to make it work.

To minimize camera shake you have to use Exposure Delay Modo, it is in the pencil menu 31.

Cheers! Rene'
