No. It is a very poor quality lens, and an extender will only make it worse. I understand you are looking for a magic bullet to get you more focal length. But extenders will reduce quality, period. Put one on a great lens with a fast maximum aperture, and you will get great results. Put it on a $200 plastic lens and you will not get those great results, and you won't have autofocus, and will have to manually focus using a very dark viewfinder. What is it that you are attempting to accomplish?
