In the manual for the camcorder, it states that the adapter is for lenses which have manual focus only. I think it may have lost something in the translation from Japanese as it may mean lenses which have a manual focus switch fitted. I have an EX1 Hi camera and the EOS adapter does give full AF, albeit a little slow. I want to get the XL lens adapter for my new toy but at £339 if it doesn't give AF, it seems a little expensive. Perhaps someone can oblige with their own experience of this piece of kit.
