Is using Mirror Lock Up Mode the same as using Live View in terms of vibration?

Probably a question that's been asked before but I haven't come across the answer... I played around with Mirror Lockup Mode yesterday and was comparing it to using Live View, which I understand also holds the mirror up, and I noticed that when you press the shutter button to take the picture the response time when in MLU is much quicker and quieter than taking a shot in Live View. I had been under the impression that Live View was equivalent to using MLU in terms of limiting vibration, but that experience made me think not. Can anybody clarify this?

I'm not exactly sure, but I think in live-view it puts the mirror back down when you press the shutter, to reset the sensor I suppose, then does a normal exposure, like you would get with a regular shot.
I think mirror lock up just pulls it up, but doesn't activate the curtains. Then it activates the curtains with the second press.

I'm sorry, I accidentally posted this in the lens forum -- meant to go in the EOS forum. If a mod wants to move it :)

As to the above post, yeah that's what it sounded like it was doing in Live View.

Wow, that answered all of my questions... thank you :)

Cliff notes:

-Newer cameras, like in the 5Dii and 7D, have an electronic first curtain which allows the sensor to be reset without any moving parts, therefore Live View has replaced MLU mode

-Older cameras, like my XSi, have to still physically drop the first curtain to reset the sensor in Live View and therefore MLU is a separate function. On these cameras, MLU is better than Live View in terms of reducing vibration.

It depends a bit upon which body you have, but in general, NO they are not, Live View silent shooting has less vibration than MLU.

In Live View Silent Shooting, both the mirror is up and the shutter is open. The exposure is initiated totally electronically. In MLU the mirror is up but the shutter is not open, and the exposure is initiated with motion of the physical shutter opening.
Here is a post where I demonstrate the small improvement in IQ with Live View Silent Shooting over MLU

ACtually liveview silent mode 1 or 2 lead to the LEAST shake blur of all, better than regular mode and MLU. Silent 2 supposedly does a tiny hair better than 1 perhaps.

This is an interesting discussion. I have one question related to it. On my 60D, it seemed that Silent Mode 1 was the default - what the camera was set to when I bought it. Forgeting about Live View, but just thinking about regular Viewfinder shooting, does anyone know what exactly Silent Mode does? From the manual, it seems that it does not slow down the burst rate at all, so there seems to be no reason NOT to use it (except for using tilt-shift lenses or extension tubes).

Silent mode is for live view only I believe.

Oh gee, you're right. If you just get to the page in the manual by using the Index in the back, you cannot tell that they are just talking about Live View (the whole chapter). Thanks for clearing that up!
