If you mean the upper limit, then I have mine in expanded up to 12,800
If you mean where do you range from when you use it. I have no issues with shooting up to 5000 or so. Clearly when possible, I'll shoot as low as I can but if the situation needs it, I'll go high and doesn't mind a bit. Great camera at high ISO's

I use 200-12800 + ISO steps as EV steps custom setting. Also I always shoot in DNG and have default presets in Lightroom 3 Beta 2 based on camera model + ISO for every possible ISO with custom noise removal settings (Lightroom 2 is ok for this purpose too). 0 luminance noise removal on ISO200 and up to 75 on ISO 12800. Very convenient, Lightroom is a brilliant piece of software.

E.g. one test pic with FA31 on ISO 12800, applied only my default settings. This is a ~50% crop from the frame. Seems to be acceptable for most conditions. For me, of course.

BTW if someone is interested I can try to share my default L3b2 settings.

Sunny Florida outside, it's 100 all day.

Down to 400 at dusk.

1600 under heavy canopy, heavy shade, at very late dusk.

Never use auto, but I mostly shoot in M mode anyway.

I shoot in M mode normally so its usually on 200. But recently I shot an indoor Native American Powwow using 2200 up to 3200 and it went beautifully.

After posting earlier I had to take my son to the game store. It was life or death to get that new game he's been saving for, you know the drill.

Anyway while waiting I took a series of shots in normal store lighting. Not very bright. The first is ISO 200, f3.5 1/15th to give some idea how dim the room was. Don't let the look of the image fool you. The near wide open Tamron 28-75mm, at a too slow shutter speed, should tell you it was too low to get a crisp shot at ISO 200, without a tripod.

Second is ISO 12,800 which is really more than I needed. I took it just to compare. f7.1 and 1/320th. That's such a huge difference. No camera shake and lots of room to play with creative controls. Like opening up the lens etc for certain situations. Since these were not tripod shots and the lens was not directly pointed at the same case cover, the slight variation in exposures, is most likely that the camera was pointed at different things (Center Weighted).
But the point of this post is, that if you don't have to crop a high ISO shot from the K-x, it can really do an excellent job at 6400 and even above. I can't wait till we see the K-8.

ISOmetrics

It's wherever it needs to be to get the picture to my satisfaction. (There, is that weaselly enough?)

For cute little copulating bugs and hard industrial objects, low. For midnight street brawls and gritty legislative sessions, the sky's the limit. NOTE: Burning buildings and auto-da-fe's give plenty available light. But for total darkness, I'll use my Sony DSC-V1 in NightShot mode with an extra IR light. Or there's always the flash-bang grenade.

mine is set to auto 200-5000.

For those that use the extended iso range, do you see better quality with iso100?

Short answer: yes. Artificial low ISOs have historically been problematic and best avoided, but in the K-x ISO 100 simply yields even cleaner shadows with no highlight loss that I've noticed. I love it. Falk Lumo's analysis of K-x RAW files also found that some interesting and unusual things were happening with the K-x ISO 100 files, affecting the signal response above a certain point.

Preferred is 100 but that is not always possible. If i'm shooting in a very low light situation I will try to up the apeture and slow down my shutter speed, but like everyone said, the Kx is great at high ISOs so if apeture and shutter speed do not fix the problem then i'll up the ISO. I see almost no image quality (grainy-ness) up to about 1800 but ill go higher if needed, isn't that one of the reasons everyone bought a Kx, for the low light capabilities?

Hey, opiedog, here they go. Shoot some test pic on every ISO possible, use "Make defaults specific to camera ISO settings" and set "Develop > Set default settings...". Or use it just like any other user preset, if you like it.

BTW I don't use ISO 100, this makes sense to me. Expanded ISOs over 6400 are also just a darker pics with K-x software positive exposure correction under the hood.

I don't use auto ISO, preferring to adjust as needed. Maybe it's a control freak kinda thing! I use what ISO I need; usually 200 or 400, and 1600 or 3200. I rarely seem to use anything in between.
