I was trying out my new Sigma 70-200mm 2.8 EX DG APO Macro HSM that I bought from a forum member and discovered that when using the lens in live view, it will not autofucus. It just shoots from one focus extreme to the other three times and then stops on infinity focus and says it is in focus. There are zero AF issues when using through the viewfinder. Has anyone else had this issue? I've tried all the AF settings I could think of.
Edit: I am using a K-3, latest firmware. The same thing happens when using a K-x.
Thanks!
