I highly recommend visiting the Lens Test FAQ section of this website. [url="http://www.opticallimits.com/Reviews/lens-test-faq"]http://www.photozone...s/lens-test-faq[/url] Scroll down to the bottom of the page, and you will see a procedure outlined in the answer to the last question: "How can I find out whether my lens has a problems ?" This will give you an idea of the condition of your lens. Make sure that you follow the instructions exactly as a failure to do so will result in inaccurate results. good luck.
