When viewing or changing menu settings in my camera with the cap off I have noticed that it keeps changing the exposure settings in the LED as I move camera around. If I adjust the menu with the lens cap on it tries to find an exposure at a very high ISO. I have read that prolonged exposure to very low light values / high ISO can damage the sensor by overheating it or the pixels. I would have thought using the menu would turn off the sensor. Is leaving the lens cap on while viewing or adjusting the menu damaging to the camera? At the risk of starting a "cap on" vs. "cap off" war should I always take the cap off while viewing or adjusting the menu? Thank you, YNY.

From personal experience using Canon and Olympus cameras no.
I soon as I take the camera out of the bag the lens cap comes offf.

Leaving the lens cap on while viewing or adjusting the menu does not affect the menu settings or otherwise damage the camera.

The risk that you mention of over-heating the sensor is if you are making a long exposure, not if you are metering. So AFAIK, you are safe.
I understand that, at list on dSLRs, the metering is not done with the sensor (except while on live view).
If I am incorrect, please let me know

Do you have AutoISO enabled?

The D7200 is a DSLR. No light will strike the image sensor until the mirror is out of the way, which won't happen until the shutter button is depressed, or you have locked the mirror up. Keep the mirror down, the viewfinder closed off, and your finger off the shutter release, and it won't matter whether your lens cap is on, or off.

Might be light leaking in from the viewfinder making its way to the metering sensor.
But the light metering sensor can have light shine on it for very long time without any problem.

Except that the original question was why there were varying light meter readings with the lens cap on.
My D810 has a built in cover for just this purpose. Light infiltration from the eyepiece is less of an issue when your eye is next to it.

The OP didn't say so. He said without the lens cap on the exposure varying and with the lens cap on it find an exposure with a very high ISO. Simply because it sees no light and he has the camera on auto ISO. Even with light leak from the eye piece the light level is very low and the camera still automatically set for very high ISO if auto ISO is on.

His camera comes with a small piece of plastic that he can put on to block the light. Most folks don't even know it's included with the camera.

I would ask Nikon directly about your concern if I was you.

Nikon tech support people would love those questions. Those are easy questions for them.
