5d2 mirror lock up and timelapses

I recently acquired a 5d2 so I'm still learning it, I'm coming off of a t2i. I've been doing a bit of timelapse lately and I thought I had read something on here that you can use mirror lock up to keep the mirror from actuating for every single timelapse still. Is that the case?

Also, how do I enable mirror lock up? I've played around with the custom settings but I can't seem to figure out how.

If it matters, I'm running the a very recent release of magic lantern on this camera.

Set C.Fn III -6: Mirror lock up, and set it to 1.
It's also in the manual. Look for MLU (Mirror Lock Up.

Good luck

Once you turn Mirror Lockup on in the Custom Functions menu, you have to press the shutter once to move the mirror up then again to open the shutter and take the picture.

I think this is what I was thinking of:

I have to try and see if this will work with the built in intervalometer in ML but if it will, that should be a lot less wear and tear on the camera when taking time lapses.

The mirror lockup is a great way to take photos and gives the photos a bit of a sharper image. Bruce Fraser illustrates it in his book, "Real World Image Sharpening with Adobe Photoshop, Camera Raw, And Lightroom."

I use a remote control to flip up the mirror with minimum camera shake, and two seconds later take the image.

BTW, it's a great book.
