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)"
NOISE REDUCTION
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.
