For instance, if a 5D is acceptable at ISO 3200, what are the results when underexposed two stops, ISO 12,800? Somebody turn out the lights and give it a go, okay? I would, but my gear is not at hand. -Chris Lawson -------------- Original message ---------------------- From: David Young <telyt@telus.net> > Nick Roberts wrote: > > >When UK's "Amateur Photographer" magazine reviewed the > >DMR, they similarly bemoaned the limiting of the ISO > >range because of the excellent capabilities of the > >device, and were confident that it could cope not just > >with 1600, but with 3200 and that it was thus an > >opportunity missed.
