Tried with 800/1600 before also but :thumbsd:
Good enough for small pic viewing but not printing :think:
There is a noise reduction setting under the menu. I always set it to low. Then any touch up will be from PS
Some quotes from the manual:
"To avoid picture noise, we recommend decreasing the ISO sensitivity, setting [NOISE REDUCTION] in [PICT.ADJ.] to [HIGH] or setting every item except [NOISE REDUCTION] to [LOW] tot take pictures. (P83)"
HIGH The noise reduction effect is enhanced. Picture resolution may deteriorate slightly.
LOW The noise reduction effect is reduced. You can obtain pictures with higher resolution.
