<p>I have the (AF confirmation) RZ to Canon, works fine, but shipped broken, after they sent me the wrong adapter (rb), and then my AF chip was busted, and the tripod mount was loose. Nothing a bit of epoxy and a little dremel can't fix. Great design, and If it wasn't for the poor build/quality control, Id recommend it. (if anything pick it up in person to make sure yours isn't screwed up). </p>
