It looks to me more like camera shake. What was the shuttertime?

Regards

Looks a little like motion blur as nothing is in focus. What was the exposure settings?

Some Exif data or at least the shutter speeds would be helpful.

But looking at last shot the girl behind and the arm look about the same amount in focus to me so I'm still guessing actual focus point is where you are expecting it. There is motion blur with the girl at the front - she is moving.
This is assuming quite a slow shutter speed.

Ok just saw your post and I think:

1. First shot is blur related to a very slow shutter speed.
2. Second is motion blur with the girl moving (1/60 still pretty slow).

In brief - Need higher ISO, faster lens or flash to fix this.

Indoor shooting in poor light can be a challenge. There are many people on the forum that have way more experience than me, who will no doubt offer advice. However from my perspective:
1. Are you using P mode? Generally P mode does a pretty good job at selecting the right balance of shutter ISO and aperture. However once aperture is maxed out (largest aperture which equals smallest f number), and ISO is maxed out (highest in the set range) then the only thing left to change is shutter speed. The problem is when the shutter speed gets down to such a low speed then anything that moves or even if the camera it self moves causes image blur.
2. I'm guessing your lens is at the 55mm of its 18-55 range and therefore f5.6 is as fast (widest aperture) as it goes.

If the above is right then you can try:
1. Using the pop up flash (or better yet an external flash unit). A diffuser on the flash will help prevent washed out or unevenly lit scenes.
2. You can increase the ISO range further to 6400 (or even 12800 but not so good). However image quality will suffer. If you only need small sized prints then this is an option.
3. If you prefer working with natural light (and there is certainly merit to that) then the other answer is to buy a "faster" lens (which has a bigger aperture). This can be anything from a new lens like FA50 f.14 to an older (and cheaper) second hand lens like M50 f.17. There are also faster zooms available but you do pay more for these. Depends on your budget.

All good advice above. You need a higher shutter speed to shoot moving people. To shoot in lower light, you need higher ISO and/or more light and/or a faster lens, just as Jonathan suggested.

* Faster shutter: Even with SR on, you should try for the 1/FL rule. At 50mm, use 1/50 second shutter; at 20mm, use 1/20, etc.
* Higher ISO: Noise can be fixed (somewhat) in PP. Shake and blur can't. Set ISO as low as possible but as high as necessary.
* More light: If you can't turn up room lights, use bounce flash. Or put a cheap diffuser on your camera flash: a thin infant sock.
* Faster lens: Faster is usually better. Unfortunately, wide apertures (f/1.4-2) give thin DOF, so only your focus target is sharp.

I pretty much only use the 18-55 indoors with flash, or with the camera braced / 'podded, or at high ISO. Fast (f/2.8) zooms are expensive. Some zooms faster than the 18-55 can be found pretty cheap. My F35-70/3.5-4.5 and Promaster (Tamron) 28-70/3.5-4.5 were only US$10 each (but I was lucky) and can be found used pretty cheap. Compared to the 18-55 those are about one stop faster at 50mm, which can be enough to stop blur. If your budget can stretch towards US$200, the new DA35/2.4 would make a BIG difference. Good luck!

For indoor shots pick up a Fast Prime - FA 50mm F1.4 is quite accessible, DAL 35mm F2.4 for about $250 each, and I've come to love the FA 35mm F2 - for example the attached pic of a neighbors kid at an indoor play place birthday party - He's on the move but I was able to freeze him at 1/160s

i am the only one seeing the backfocus?
Sure, there is motion blur, but in both picture the kids in the background seems to look sharper than the subject

Hi, Glad to see a forum dedicated to the Kr. I am fastidious about getting a sharp image. It worries me that some people see that the KR has some focussing issues. I havent sold my K20D yet, so will have to be careful. But in the photos shown, I would have to agree generally that it would not appear to be the fault of the KR. The first would appear to be camera shake or subject movement, due to a slow shutter speed. In the second one I would again suggest that it is not the KR, because the second child and the arm in front are in better focus than, the subject.

Hope I am right because last thing I want is problems with sharp pictures, Sold the KM and my sigma lenses because of sharpness problems, dont want to have to sell the KR. K20D is fine but no video.

Exercise: Set ISO to auto up to 3200 then, using Tv Mode shoot kids playing around indoors at 1/10, 1/20, 1/40, 1/80, 1/160, 1/320. Observe for yourself.

Then go to the library, or the local bookstore or photography shop and pick up Bryan Petersons "Understanding Exposure" Its worth the few bucks to buy and clarifies so much.
