Shooting handheld in low light. I've been shooting wide-open at 1/15th with
that lens just after sunset a couple of times. In those cases I locked up the
mirror since composition wasn't so critical. I don't like shooting handheld at
1/15 with any lens!

They can help when the sun is _just_ outside the frame. I've managed to
get my fingers in the frame a couple of times when shielding the sun at the
corner of the frame. A 100% viewfinder would be rather handy at times :)
