When do you mostly use mirror lock? I really haven't found a case where I thought this might be usefull.
Thanks,

Mirror lock is a function present on most SLR designed to reduce vibration introduced by the movement of the mirror during the shutter release cycle. For long exposures, is not mirror lock but a tripod (or other suitable camera support) what you need.
Mirror lock is particularly useful when you work with MACRO or telephoto lenses, as these usually will magnify any small vibration in the system. Another time I most often use it is in landscape photography in conjunction with a tripod.
As previously stated, mirror lock will be most useful when combined with a remote shutter release, but if none is available you can use the camera self-timer function. If you do, and your camera offers a choice, use the longest possible delay - 10 sec on mine.
