As for noise, I've been very impressed with my 30D's handling of noise even at ISO 1600. I've tried shooting at 3200 in low light just for fun but the results were not that great.Number Twenty Nine wrote:most cameras these days will have a noise filter setting of some sort. (off, low, high). The NR you are talking about is dark frame subtraction for when you use long exposures - typically more than 2 minutes.
a small sensor camera like the Panny will have hardware noise filter that you can't turn off plus a user selectable value. The user selectable value is for high iso jpgs.
my T2i has both settings in the C settings menu.
here's a long exposure I took this morning with the T2i and a ND1000 filter - 50 seconds
