I found the response from Joe Tainter to Godfrey's question quite illuminating. When asked how he managed back in the film days, he seemed to state that basically he rarely if ever used ISO 1600. Sure, the *ist-D at 1600 is noisy, especially if you cheat on the exposure. Follow Paul's advice, and over-expose by half a stop - you'll get ISO 1000+ with tolerable noise levels. Definitely not as good as with a good ISO 800 film (such as Portra 800), but then the faster films were noisy, too. I find the *ist-D at high ISO to be comparable to the high-iso films such as the Fuji 1600. I don't think small-format cameras based on any technology do all that well at high sensitivities - noise is always a problem. This is definitely a case where larger formats help; the lower enlargement from a 6x7 negative, say, gives a natural smoothing of the noise. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
