I just found out.

When shooting from a tripod and having to use a long exposure time. Somewhere between 1/30 and 2 seconds, the exposure can be completely vibration free, by using the self timer. The self timer lifts the mirror as soon as the release button is pressed and keeps it up until the exposure is finished. But did you know, this happens only with the 2 second setting? The 12 second setting does not rise the mirror from the start, but it works just like a normal exposure. Regards, Horst

On a similar topic - HOW is the mirror held up for prolonged periods (2 sec timer and live view)? LV will time out if you leave it for too long. Can repeated use of it wear anything out or otherwise damage the mechanism?
