The D and the Ds have the same sensor and very similar characteristics for all intents and purposes so I have no compunctions about answering from experience. I've found that from ISO 200 - 800 the noise levels are low enough that you can pick you ISO for the Shutter speed F stop combination yo

Hey Folks, Thanks for the speedy comments re: sensitivity. So my follow-up question (and then I'll try to get some work done today!)is there any reciprocity failure issues with digital detectors? I'd think the detection was fairly linear with long integrations (exposures), but I'm guessing tha

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

Tom Van Veen, There's a good comparison of sensitivity vs. noise for the Canon D30 and EOS-1D at: http://www.dpreview.com/articles/canoneos1d/page9.asp It looks like the 1D has usable sensitivity up to 800 ISO equivalent, at least. --Mike - This message is from the Pentax-Discuss Mail List. To
