Title: Nikon D800 changes settings in Manual mode by itself
Post by: figure1a on June 05, 2013, 11:06:43 pm

I put the camera in manual exposure mode and set it to 1/1000 at f4. Sometimes after I take a shot, it changes the exposure to something like 1/800 at f3.5. Is there a setting that is doing this? I have another D800 that always stays where I put it. But it seems like this camera is set to "make a suggestion" for me which I don't want.

This may depend on a lens. Some lenses change aperture with change of focusing distance.

It's a constant f2.8 lens. But also the shutter speed is changing. There are so many option in the menus that I cannot figure out what would be doing it.

Yes, but some "constant" 2.8 lenses are not that constant:) they change depending how for you focus.

I have never seen this kind of behavior and I am not aware of any setting that would impact S/A set by user in M mode.

The only thing I can think of are the 2 separate banks of settings between photo and film in live view, since each of them keeps their own setting. Did you not change that mode by mistake?

Cheers,

Have you enabled bracketing?

I'm seriously tempted to repost my shot of my Nikon f3.

Hum... that happens to me a lot also.

A pro photographer once told me it was a susceptibility problem. Not sure what he meant?
