I would have to say that I would rather have what little internal volume must be devoted to the logic instead devoted to providing more juice. > Pentax' decision to go with a standards-form-factor battery means > that they can't get that kind of information, so the indicator is > just a rough guide to battery state.

What more do you really need? ;-) Well, the plan here is to have backups ready from the get-go, and replace them when they show half-full (as soon as convenient). Hopefully, I won't end up finding out how many shots I can take when the indicator says "empty" - finding "n" would require "n+1" attempts - <g>. Fred
