Hi again Bruce--
  I've been researching the deal you got on the Minolta.  Looks like a great
deal on a very nice camera if you can wait long enough to get all the
rebates.  One thing I did notice in researching the DiMage 5 is that it gets
quite warm.  One reviewer also indicated that the noise level was pretty
high (although optics were truly excellent).  This is probably a secondary
effect of the heat.
  If I understand the issues correctly, this would certainly indicate that
you'd need very frequent black shots.
  Michael
