unlike many wide-angle telephoto lenses on Lenses are only one focal thought, Tele. You s.Deinem camcorder zooms back, then the edges are visible.
Or you can see the edges synonymous then, if you're completely zooming? That would be not so great in fact. In this case, I would try to exchange the on Lenses and pay attention to when the next purchase should be taken that the converter fits the camcorder lens.
