I agree with those who said you might be too close but there is another possibility. Does the lens have image stabilization, and was it on when it was on the tripod?
No image stabilization in the lens as I have a Pentax Kx and if I'm too close the camera will not let me take the shot...the only thing I can figure out is at that high of a f-stop and on AV mode I'm getting a slight camera shake even using a tripod which is an inexpensive Dolica AX620B100 62-Inch Proline...I have tried f-32 AV mode same tripod with no adverse affect...go figure.....
