It doesn’t autofocus because there is no focus involved in the “fisheye”/”macro” extension. If you have a lens that uses autofocus, it will probably still sort of work with the “fisheye” extension. The macro will confound autofocus because it’s just too much of a distortion from what the sensors expect. It’s probably worth the money if you just want to take snapshots, but if you want to take truly professional-quality pictures and/or make very big enlargements of your pictures, it’s probably best to save your pennies for a genuine wide-angle lens.
