Thanks a bunch. It seems as if nominal exposure is somewhere between 10-25 seconds at f/1.8 and ISO 400. However, I just have to bracket the hell out of each shot, and then pick the best when I get home. Digital is wonderful though because I can at least get into the right ballpark by looking at the display. When you're bracketing 20 second exposures, with 20 second noise cancelling wait periods, it's very easy to spend half an hour just trying to nail the exposure by bracketing a shot. I did figure out last night that I can save a lot of time by cranking the ISO up to 3200 to figure out the nominal exposure and composition, then crank it down and bracket at 100-400. Beyond ISO 400 and the K20 gets too noisy for the long exposures. That reminds me, I did some test shots with both the K20 and the K100 to see how the K100 did in comparison. I have come to the realization that I want a D700 with a 35/1.4 and a 50/1.4 or maybe even a 50/1.2. Maybe, by the time I can afford one, Pentax will have something with that level of high ISO performance. The problem is, that for night photography, assuming the 35mm form factor, I'd pretty much need "full frame" in order to get in the range of f/1.4 with a 30ish mm on a 35mm angle of view. I don't know of any 20mm f/1.4 lenses. At least not affordable by mere mortals. > > Malcolm > > > -- > PDML Pentax-Discuss Mail List > [email protected] > http://pdml.net/mailman/listinfo/pdml_pdml.net > to UNSUBSCRIBE from the PDML, please visit the link directly above and follow > the directions. -- The first step is learning to take great photos, the second step is learning to throw away ones that are merely good.
