Do it. I picked up a used copy (only way to get this lens!) and have not regretted it. It has become one of my favorite lenses. It's so much easier to carry around that any of my other telephoto lenses and it is less conspicuous also. But the image sharpness and color reproduction are excellent. I just shot a play last night and the bulk of my images were with this lens. I can not recommend this lens highly enough.
