Mine seems to work the same way. I am just in the process of
checking it on the minimum iso setting (so far it has held the
shutter open for a couple of minutes). At iso 3200, it gave an
exposure of about 3 seconds.
This is with an A 100mm f2.8 macro on the camera, set to f22
with a screw in metal cap attached. It should be as light thight
as they come.
Well, it has been going for about 8 minutes now, and I will shut
it down. No sense wasting the batteries to death.
