I was under the impression that the S7000 could only use ISO-800 at 3MP however just last weekend I was using the camera in the auto setting with the flash on, the subject was about 20' away in a dimly lit room. Just a snapshot of my wife's nephew. When I checked the exif data on the file it said 4048 by 3040, ISO-800, 12MP at ISO-800!!!

Is this the case, auto allows high ISO at full resolution? BTW the image is noisy but quite acceptable and Noiseware cleaned it up nicely.

I will give mine a try and see what I come up with to test your theory, you said it was on auto with flash on? And I see it was set to 12mp mode, was that RAW or not?

12MP fine, not RAW, interested to see your results.

I was not able to duplicate your results . . . from a dimly lit room to almost pitch black, or outside under moonlite. I used flash and nonflash . . . in fact it never went over 250 ISO i stopped trying after 28 photos (batteries finally died!) Going to have another go at it tonight after a fresh charge though.

I will try it again to make sure it wasn't some fluke.

Just tried it again,

First test: distance about 20', focal length 47mm, f3.1, 1/128s, ISO-640 12MP fine

Second test: same distance focus on darker area of scene (camera would not focus), focal length 47mm, f3.1, 1/128s, ISO-800 12MP fine

Third test: same scene and distance, manual focus, focal length 47mm, f3.1, 1/128s, ISO-800 12MP fine

No fluke, my camera seems to use 800 with full resolution when set at auto with maximum zoom, 12MP fine, flash up. Without the flash the ISO stayed at 200.

No luck, stays at either 200 or 250 ISO no matter what I do. I will say that I pre-ordered this camera when it first came out, so maybe something changed in later models? :?

Well it isn't documented, I purchased my camera in February of this year. I can send you a file right out of the camera if you want to checl it out (with the exif data intact). Just pm me an email address that can handle a large file. The noise is very obvious but it is a nice even texture which would look alot like film grain, especially if it was converted to B&W.

I guess from now on if I am using the internal flash indoors I will leave the camera on auto.

Mine does the same, (Flash ON, 4048x3040, fine, 1/125, f3.1, ISO800). I'll do some tests tomorrow to see if is actually ISO800 and not some bug in the firmware that makes the exif data say it is.

Nah, it is good, I believe you, there must have been something changed during the production cycle along the way. I am planning on picking up an S9000 for my trip to Italy anyway so it doesnt matter to me really.
