On some Canon DSLRs, a secondary use may be to prevent the mirrors from falling out ...
the mirror lockup is usually done prior to a long exposure (anything more than a second, i suppose, or where you can no longer handhold it).
This is to prevent any movement when we trip the shutter, else the mirror slap may cause some movement for the more flimsy tripod setups. Normally used in conjunction with either a timed release or a remote release.
It's actually more useful for intermediate exposure times (i.e. anything that cannot be hand-held to about second or so). For very short exposures, vibrations are not an issue. For very long exposure (seconds), the vibrations will decay so quickly (tens, maybe hundreds of milliseconds) that the time during which the camera shakes is a negligible fraction of the total exposure time.
The conventional use is to eliminate the strong vibrations caused by the mirror movement milliseconds before the shutter opens.

ah well, i usually do it when i have it on a tripod :dunno:
So ideally mirror locked up is used for long exposure and tripod mount!
But really is the difference a lot? Will it be obvious if i use or do not use it?:dunno::think:
Thanks again!:cheers:
