you have to turn the feature on in custom functions, then press the shutter button fully to lock up then press again to take the shot. This is how it works on the 30D check your manual to be sure.

Mirror lock up gives allows you to raise the mirror up exposing only the shutter to the lens before you execute your photograph meaning that when you come to take the shot, there is no unnecessary vibration/shake from the heavy mirror. When you press the shutter button for the 2nd time its only the light shutter to be raised.
To enable it you will have to turn the function on which is within the custom functions menu.

Get yourself a Cable/Remote release too!!... then you won't have the added risk of knocking the body with your knuckles in the dark when closing the shutter from using 'Bulb'
Must get round to some Looooooong exposures myself!!..

Watch this:
Then note that the mirror flicks up pretty violently, mirror lock up means the mirror flies up first, then you wait a few seconds for it to settle and then you press the shutter button again which will do the curtains (creating the exposure). Basically stops your photo getting any kind of blur from camera movement caused by the mirror flicking up.

Check whether your camera instigates mirror lockup when you set it on one of the delayed timer modes. On the Sony if you use the 2 second delay timer, i.e. you press the focus button to focus, then press it down further to take the shot, the mirror will lock up then two seconds later the shutter will open and the shot will be taken. The advantage of this is that you can get away without using a remote shutter release cable, as you can take your mitts off the camera in the two second gap. The remote release cable is always going to be preferable though, but at least you can try it and see what the fuss is about re: mirror lockup.
Virdi,
a quick tip - you can customise functions on your Canon 50D quite easily - check pages 171 to 186 of the manual.
Page 173 gives a breakdown of the settings that can be customised - one of them is enabling Mirror lockup on/off for all shots.
Rather than wading through the various Menus and trying to figure out where Mirror Lockup is, you can register this setting as part of "My Menu" - page 185 details how to do this.
You can then simply keep scroll to the "My menu" once you have it registered (along with any other settings you want to enable) and then turn it on and off. Its quite a quick way of accessing some of the cameras settings.
