I've been panicking because I thought something was wrong with the shutter on my D300.It was making a strange noise.
After some googling it appears that because the camera was in 14 bit mode,the shutter does sound differently. Phew

Ummmmmmm could use that as a trick on my friends D300, give it to someone else then bring up in the conversation that he has used it last and must of broke it. I love being evil.

I can't imagine how a difference in data processing can have any effect on what is surely a mechanical noise. Are you referring to the actual noise of the shutter - ie with the mirror locked up - or the combined mirro shutter noise? How is it different?

Its to do with shutter delay in Raw/14 bit mode.I cant be bothered to look into it any farther .
I thought I had a real problem because whatever shutter speed I was choosing,the click sounded the same every time.When checking histogram,all appeared ok. A slow shutter speed sounded as if something was loose inside.
It certainly had me worried for a while.

I've just tried this with mine, and the 12 bit shutter release noise sounds slightly higher pitched. I shot in manual mode 1/80 sec at f5.
Weird.

I am utterly intrigued about the reasoning behind this. Might have to email Nikon....
EDIT: OK, on nikonians we have:
This - mirror stays up longer.

It's clear that they don't really know either........
Must admit.... I think I'd go with the bug theory. The 'keep the mirror up so you can't take a picture' idea sounds unlikely. If my 20D is still trying to process an image when I press the button I simply can't take a picture and I get a "Busy" warning in the finder.... does the Nikon not do the same?...

I also think that this is clutching at straws. By the same token, when I have filled the buffer during a continuous burst the mirror doesn't then lock up until the buffer is free, I simply can't take any more exposures until there's space.
Perhaps (and this is merely conjecture) there is a mechanical advantage to using a slower mirror movement; since a 14 bit image will take time to process, the camera can 'relax' into the slower pace of life. In other words the camera slows down simply because it can, and saves mechanical wear/tear...? No point going balls out if you don't have to.
