All of them! I prefere 200ASA, but I often use 400ASA too. For concert shots and available light indoors I use 800-1600 ASA - somtimes even 3200 ASA, but the latter will often require using Neat Image for noice reduction, which means loosing sharpness. Regards

Rice, Ph.D. > Invasive Species Specialist > Invasive Species Initiative > The Nature Conservancy > V: 530-754-8891 > http://tncweeds.ucdavis.edu The lowest ISO possible would normally be your best choise. I'd bump it up to ISO 400 to shorten exposure, but not beyond that for best results (That said, I've gotten good results already at 800). For long exposures, turning on noise reduction and shooting at 200 would be the ideal setup. Noise will show up starting at 800 and becomes objectionable at 3200 (1600 looks alot like 1600 film, kinda grainy). -Adam
