Noise is fairly minimal, i'd imagine once printed you wouldn't even tell.

OK now I'm jealous... you have a K7 and Calamari!

Nice example of the K7 and Tungsten lighting.

Just found this, seems very good up until 1600 then gets very bad very fast!!!

Also if anyone has any low light video samples that'd be great too

I've seen this one:
Ed, I disagree with you. ISO3200 looks better than ISO1600 on my K10D. ISO6400 looks more than usable. While there is chroma noise in the shadows, the brighter areas look good, and detail is well retained. The K20D images have less chroma noise, but also slightly less detail, and they are also exposed maybe 1/3 stop lower, which is going to mask some of the noise.

I've seen a fair number of these comparisons and they all show the K-7 exposing brighter than the K20D for the same ISO, Aperture and Shutter Speed settings. The K-7 CMOS must be boosting the signal more than the K20D's. What I'd like to see is comparisons at the same exposure values, that is, with images from both cameras being equally bright independently of Aperture/Shutter settings.

I'd also like to see these comparisons with the K-7 firmware update installed.

the chroma noise in the 6400 iso k-7 is 10x worse then the k20d....
Would any sensible person buy an APS-C camera for use at ISO 6400? That is just plain nuts. If you really need to work at that ISO, you need a FF camera. So, please, everybody, stop bitching about ISO 6400 noise as though it is a fatal flaw for the K-7. None of the other cameras in its class is great in that range either, even if some are better. It just isn't what these cameras are built to do.

This is what matters to me: performance at high ISO in low light. The pics here from the theater are impressive but I'm not sure what's the camera and what's Silkypix. Here's a pretty typical shot from my K20D at ISO 1600:



NO noise reduction applied. Minimal post-processing in Lightroom 2.4, mainly to increase exposure in the middle. The face is not bad; the noise is apparent in the white background, which is pretty normal in my experience. To be honest, I think this is pretty good. I'd like to know if the K-7 is much better.

Sorry I haven't updated this since I got my K-7 on friday.

Here's too low light samples at 6400 iso

First is straight from cam



Second has ONLY had the COLOUR noise removed leaving a nice film type grain effect instead of it being blurred and smuthery.



But I wouldn't exactly call it usable if you print it it doesn't look too good but I suppose on a newspaper you might get away with it but not on proper photo paper.

I'd use up to 3200 no probs and 6400 as an emergency to capture a photo you otherwise would miss.

First of all, black and white is a lot more forgiving of noise than is color. If for some reason I had to shoot at iso 6400, I would just go to black and white and let everyone think it was an "artsy shot." The other thing is that "useability" of photos really depends on what you are doing. If you are a wedding photographer, you probably are going to tolerate no noise in the formal shots, while some noise in other photos that will never be printed at a large size is probably tolerable. At the same time, I don't see iso 6400 really being useable on an APS-C camera in the near future.

C'mon, it's the classic "I wanna take a photo, but I'm to lazy to move from my seat" shot!

Ummm. I'm not sure if you want C&C on those photos, but they are all, well, just awful.

And why force us to wade through all your Facebook snapshots when you could have just selected one or two that were at least relevant to the subject of this thread - K7+ low light - and featured them here directly.

Grrr. First feet photos, then this.
