For all those wondering why we have to turn off the IS when on the tripod, I did a quick comparison. My subject is my bare-bulb maglite. I mounted the camera on a tripod, put it at full zoom, ISO 80, F8, 15", 12-15 ft. away from the subject. I had to do major cropping in GIMP to magnify the light source.

Wonder if this means that it's good to have a shakey hand when taking longer exposures? I mean, what happens if you were ultra steady shooting a 1/4 sec shot?

Good point, maybe it is better to have shakey hands when doing long exposures so that IS kicks in. Maybe that's something I have to experiment on.

Regarding the larger aperture, I can also experiment on that further. I used a small aperture in the experiment because I didn't want to overexpose the light bulb. I'll do an experiment on the larger aperture outdoors, probably on a distant street light.
