Long exposure times result in longer processing time before an image is 
saved.  This is only really noticable as exposure time grows to a 
half-second, and can actually take ten seconds or more if you took a 
30-second exposure.  I'm not sure what the mechanics are behind this 
phenominon; I suppose it has to do with processing together multiple CCD 
  sensing cycles, or something like that.  Note, during the processing 
time of which I speak, the SD light is not on.  It comes on after that, 
as the image gets saved to the card.

You probably did hit the nail on the head when you mentioned taking 
several shots in quick succession.  The camera's buffer holds something 
like five shots, and if you take a bunch in a burst like that, you'll 
notice some lagtime in writing out multiple files to the SD card.

And Rob may be right, I could have a bad sector. I never thought of running 
disk check, do'h.

But, actually, I think it is the first thing you said. The only thing I can 
think of when it may happen is low light shots, where I *am* taking longer 
exposures. I am going to pay attention and see if that is when it happens.

Plus checking multiple shots and disk checking. This is, actually, something 
that has been puzzling me from the beginning. 

I vote for #1. I take a fair number of low light shots. And I only notice the 
light staying on later -- it is quite possible I thought it was done writing 
to card, but it was still processing, THEN I look down and see the light on 
and think it was on the whole time. But it just STARTED writing.

Marnie ;-)  Boy, I'll be glad to clear this up.
