Thanks for posting that image, Hershey. I now can say that I concur with your feeling that it was nothing more than motion blur. There are two bits of evidence. (a) Visual inspection of the blur pattern, and (b) the EXIF data that says you exposed the image for 1/8th of a second. I don't thiink your camera has any form of vibration reduction (aka, image stabilization). Because of that, you should use the modern version of the old rule thats says that to hand-hold a camera the shutter speed should be faster than twice the focal length. So, if you want to use a 30 mm FL, your shutter speed should be faster than 1/60th. Similarly, hand holding a 100 mm focal length would require you to shoot at 1/200th of a second.
In the case of the photo you posted, the FL was 24 mm, so you should have used 1/50th of a second or even faster. BTW, this rule isn't meant to be followed slavishly. If you have good steady hands, you can push it slower, but if you are in a high pressure situation or you have coffee nerves, go another stop faster to be safe.
HTH,

PS -
MrTom - Because Hershey's file name included the phrase, "tonemapped", it sure sounds like he (or his camera) did some work on the original image. That being said, this doesn't change my conclusion that the problem was indeed camera movement.
