I used the method put forth in the Lens Test FAQ section [url="http://www.opticallimits.com/lens-test-faq"]Here[/url]. I followed the directions exactly and was able to determine that my lens did in fact have a centering problem. I suspected it had one, but this test gave me the confidence I wanted before sending it in for repair. The repair facility confirmed my findings and repaired the lens.
If I forgot to do so earlier, thanks to whomever included the test instructions.

An alternative approch is to use the Zeiss Siemens Star Chart as described in http://www.lensrentals.com/blog/2012/05/...a-makeover
