Okay, I don't know what you mean by that, whether you're being sarcastic, but I guess "low light" doesn't exist any more in K-5 land, so maybe that's what you were thinking about.
Anyhow, the low light I referred to originally is hockey arena lighting. With my K20D the best I could do yesterday was ISO 1250 at f/3.2 using my FA 50 f/1.4. My shutter speed averaged around 1/200 sec. for most shots. This wasn't enough to freeze action and prevent some blur, but any higher ISO and the noise would have been even worse and any wider aperture and I would have missed focus on a lot more shots since the AF was slow and missing the target most times. Like hcc, I eventually resorted to MF for better accuracy.
Ideally, I would have liked f/4 with 1/750 sec., but I would have had to push ISO to over 2000, and that would have been a noise disaster on the K20D.
I'm thinking, by what I've read, that the K-5 could have achieved f/4 at 1/1000 sec. with ISO 3200 or thereabouts and the noise would have been minimal. I'm also thinking that the AF.C would have been faster and more accurate. If so, I'll start saving for the K-5. But before I do this, I'd like to know from user feedback if this would be the case, or if I'm dreaming.
