Hey Folks,
I'm now learning how to think "digitally" with my *ist-DS. The thing that
perplexes me is setting the sensitivity. I'm used to shooting with Velvia
since minimal grain and nice saturation are important to me. What
sensitivity do people use? I'm no stranger to taking 15 second exposures to
maximize my DOF in my botanical fieldwork, but I'm intrigued at the notion
of cranking up the sensitivity on the camera to take big DOF images with a
short exposure. Could it be that I don't have to worry about the wind
anymore????? At what point would I expect to see noise? I don't see this
addressed in the manual, except in broad terms.

P.S. Please forgive me if I missed an obvious paragraph in the manual. I
*do* read manuals carefully---let's just say I'm excited about this new
camera!

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).
