When shooting static subjects (indoor in museums, churchs and others, for example) with low-light requiring very low shutter speeds (with a 16mm-20mm lens, less than 1/20 for example), i usually use MLU (mirror lock up).

I frame, squeeze the shutter once for the mirror to lock and then gently squeeze it right after to take the shot (trying to keep the framing as steady as possible).
I then review the shot to ensure the framing i got was the one i wanted and repeat the process if it failed.

This may seem a bit odd, but it really works for extreme slow shutter speeds!
