I'm not sure. Since TC's are meant for telephoto lenses it doesn't seem like it would be sharp with a wide angle lens. But I don't have one so I didn't try.
Originally posted by dms I don't have this lens but I saw the following--which discusses an "optimum" setting.

Royce Bair is one of my favorite photographers. But I'm not sure there is an exact optimum setting due to the sample variation of lenses. But I know my lens is going to be a lot easier to focus now that infinity is where it's supposed to be.
