What Joachim said.

Most likely a focusing issue.

Bob

A focusing issue with the lens, yes; you do realize the point of this thread is that the lens is behaving incorrectly?

Could be the lens or the body.

- OP already said that other lenses produce good images with the same body.

Have you confirmed that the lens produces an acceptably sharp image at infinity using manual focus?

- OP has provided images at close, medium/far, and infinity focus. All are confirmed to not be acceptably sharp for the 16-55, although the close focused ones appeared closer to acceptable.

If it does then try a series of 10 shots off a tripod focusing on a good contrast target at infinity and see how many are in proper focus.

- Why take 10 shots when he is at 1/5000 second exposure time? They would be 10 shots with the exact same (zero) motion blur, wouldn't they?

It would seem to me that you haven't read the full thread, because this doesn't appear to make much sense in that context. I don't mean to start an argument here, it just appears that OP already did the tests and got the feedback sufficient to conclude, so there's no reason to ask him for another round unless you can first explain a fault in the previous test and conclusion.
