That funky focus

I'm a new user of a K20D, i used to be a k200d user...

Since i'm with the K20D, i'm unable to get real focus, i've checked with a chart for FFocus and rearFocus but that doesn't seem to be the issue. Probably my technique is weak...Do you have any help or solution, event with a tripod it's very difficult to get perfect focus.

Here is a crop...i shoot in raw

Thanks for the help

Which lens did you use ? Is it one you used previously with the K200D ? And how far were you form the subject ?

Since you've used an SLR before I'm guessing you have some experience. At first glance it looks to me like the SR is not working. I'm perplexed, switching to a better model should give at least as good a picture as with your previous camera if not better no matter what lens you're using. If you still have the old camera and perhaps a tripod or can place both cameras at the exact same place you can compare both cameras and compare pictures.

The picture has motion blur, not bad focusing. Try it on a tripod and report back.

1/45 second at 80mm (120 effective).

Try shooting at 1/120 second exposure for handheld. Otherwise, it is going to blur.

Looks like motion blur...
Shake Reduction is not a panacea for poor technique.
Holding a camera rock steady is a skill.

Yep, motion blur as others said. Moreover, any stabilization system will be much less efficient at macro distances (I think it's even mentioned in the Pentax manual). For macros, a tripod is a must.

I think the 4 posters above me got it right, 1/45 is too slow for 80mm lens, try it at f4 with1/90 1/100 or put it on the tripod to see what happens...

What I meant to say was that this is clearly motion blur

Motion blur occurs when the object being photographed is moving and the shutter speed is too slow to stop the motion.

Not sure what is being photographed here, but it looks more like camera shake from too slow a shutter speed in relation to the (actual, not "effrective") focal length of the lens.

As others have said, that's largely motion blur. But I'd also point out that since you say it was crop, that looks like a pretty busy scene. Who knows if the camer was actually even trying to focus on the specific part of the scene you posted. Without knowing how much of a crop that was, I'd also observe that appears to have been fairly high magnification, and even f/8 doesn't give you unlimited DOF. So chances are petty good something else was in better focus - but with the amount of blur evident, probably nothing would have looked very sharp.

As everyone else has said, looks like camera motion to me.

One additional point...When shooting on the tripod, be sure to switch SR off or use the 2 second shutter delay. If the camera is immobile, SR will introduce motion. Go figure...

I agree it looks like blur caused by camera motion.

Another thing to keep in mind when using SR is to make sure to wait for the Hand symbol to appear in the viewfinder before you snap the photo. Not doing that is said to lead to blurry images.
