Since the WW-field of HG10 was insufficient for indoor shots (generally for a short distance) I was looking for the original Canon WW-Converter first. But a price close to the replacement value of the camera I did not want to pay for it. So I found this Minadax Converter with Macro lens and adapter ring for a comparatively low price. The delivery was made quickly by pulse photo, and of course I've tried the same. The quality is good, and the benefits too. You can combine prima: - WW-intent alone gives a strong effect WW (shortening the focal length, only when zooming then goes autofocus no longer sometime, but (Tele) should also decrease the intent). The picture is good, no black corners (against an adapter such as smaller diameter). - WW-intent with Macro lens gives even a slight focal reducer. - And last only Macro lens because you can practically up to the front lens zoom. Can for this price for just over 50 (incl. Shipping) are only recommended for all, which is not short enough, the focal length.
