I've searched and found my question almost answered on this forum, but then I find seemingly conflicting posts. So I'll ask my question directly:
Question:Are either (or both) of the LiveView modes on the D300 effectively a mirror lock-up mode?
I'm waiting for my D300 to arrive, an upgrade from my D70. I do a lot of macro photography with the beautiful 105VR Macro lens and I'm seriously looking forward to the mirror lock-up feature (that is not present at all on the D70.)
However I note that the shooting dial, LV and ML modes are mutually exclusive. (And I've read discussions on this forum about this.) But despite this, both LV modes work with the mirror locked up, do they not? Surely the mirror does not rattle about at the moment you take the shot?
Thanks in advance for anyone who can put my mind at rest.

The two modes are similar but different. The mirror lockup is for sensor cleaning and maintenance, and reducing vibration on slow shutter speeds/long focal lengths. To use ML you would compose your photo place the camera in ML mode then trip the shutter.
Live view does lock the mirror in the up position and allow you to use the back panel LCD as a view finder, or a PC if you have the camera control software installed. By watching the monitor you can compose your photo then trip the shutter either with the camera/a remote/or remote software.
This is most likely a very simplified explanation but that is how I understand it an how I use it. Hopefully someone else can add the technical details.

This is only half true. You cannot use Mup for sensor cleaning as it doesn't open the shutter. You have to use a menu item for that instead.
In the Liveview handheld mode, your first push of the shutter release raises the mirror and opens the shutter to allow the image to show on the LCD. When you press the shutter release halfway, the mirror is lowered to allow the camera to autofocus and set the exposure. Then when you press the release all the way down, the mirror flips up and the camera opens the shutter to make the exposure. So handheld isn't a "mirror up" kind of thing.
The "tripod" mode is a bit different. You press the shutter to raise the mirror and allow the screen to act as viewfinder as before. In this mode, you press the AF-On button to focus (or press the remote button for over a second), and the mirror stays up while you do it. This allows you to get the focus right while you're looking at the LCD, which is darn useful. Pressing the shutter _still_ lowers and raises the mirror before taking the shot, and it does so between each shot if you're shooting in continuous mode. So tripod mode doesn't seem to be a "mirror up" kind of thing, either. (Although you can set Custom Setting d9 to delay shutter activation for a second after the mirror goes up).
I thought mirror lockup for sensor cleaning, reached via a menu, is just that, for sensor cleaning; not for photos. While the Mup on the release mode dial is used for photos. In the Mup mode, you press the shutter once to raise the mirror, then press again to take the photo.
You have an option d9 under tools. It is called exposure delay mode. I use this with the tripod live view mode. It delays the suhtter about 1 second after the mirror locks up to reduce the mirror vibration. Push the ? button to see Nikon's exact description.
I am a big fan of the live view for landscape and macro. This is one of the reasons. The other is the ability to focus so precisely and easily confirm what is in focus (by using the zoom when in live view)
My D300 is 5 years old and still kicking right along in spite of Nikon's evil plans to make us spend money on repairs. Relax Bill, your camera is no more than 3.5 years old. Like mine it was designed and tested to operate for 150k shutter (and mirror) actuations. Quit sweating the the hardware and go take pictures.
Nikon put what could be a very useful feature for me on the 300S and then ruined it by flopping the mirror for no reason. I primarily shoot bracketed exposures on a tripod where using the rear LCD would be very useful. I need the exposures to be taken rapidly for HDR without the mirror vibration.
Considering the much higher IQ of the Fuji x bodies vs the D300S, I'm very tempted to make the switch. Too bad nobody is in the business of hacking Nikon firmware. That is a fix that I'd pay for.
