Unsharp pictures with 7D and EFS 17-55mm, F2,8. Peter, Copenhagen

The smoking person looks just fine, look at the suit and parts of the face. Nice and sharp.

You shoot all your images at f2.8. That gives you thin DOF. I think your first image, the face is ok, but everything else is out of focus just because of the thin DOF.

WIth the boy running, you used AI servo, AI servo also shoots when the subject is not in focus. If the boy is running fast, he may just have run out of the optimal focal plane.

So, at the moment, there is nothing to suggest the lens is bad based on these samples.

I have written some metadata fron the RAW files. Please take a look at theese pictures, i hope i have done something wrong with my 7D and the lense, i do not hope, there is somethinh wrong with the camer, the lense, og the way, they work together. Comments and critics are very welcome, but my main concern is, why are these pictures not sharper. I am considering to buy another 17-55mm, and hope its a better copy, but if the failure is mine, i will save the money for another nice lens.Greetings, Peter/Copenhagen
