Yes, try f/8 and f/10 and see what happens then.

Ok heres a few test shots, these were at f8.0, dont know the shutterspeed but it was high 200-400+ish, i think its fairly sharp. These were at 50mm btw.
Original unedited
Sharpened
edit: Hmm i did a big crop so you could see it all but it doesn't let you zoom in far, atleast not on my firefox. You get the idea though

Those look good to me... It's looking like you have a slight focus problem. This issue will be greatly amplified at larger apertures because of the shallow DOF.

any idea of thats something sending it off to be calibrated would fix, or does this happen in this lens no matter if its calibrated? |

As far as I know, the 17-50mm is supposed to be very sharp. So if you have focus problems, calibrating it should help. But... I'm still unconvinced you have a problem. The goose looked pretty good, but the head seemed a little soft. But is that the lens or just the way the goose was shot (with it's head farther away).
I recomment taking a picture straight on with a textured wall (like brick). Sometimes the lenses are out of calibration and one side will be focused while the other isn't. Make sure you are directly straight on to the wall, because that will influence the focus also.
If your lens is off focus-wise, I don't think it is off by much. |

If you happen to be manual focusing, make sure that the diopter adjustment on the camera is set for your vision. I have done this "oops" a few times.

Ok about the auto mode. A lot of people leave a UV filter on. Are your test shots without a filter?
I had a cheap polarizer that made a mess out of pics with a 70/300, but I discovered the problem within a day or so.
