Fast Delivery. The intent is delivered in very good quality. Adapter ring is made of metal, thread fits perfectly and wobbles nicht.Zur delivery include a soft carrying pouch and cleaning cloth. Bought this converter for a Panasonic HDC-SD800. Without Zoom the image corners are slightly rounded, which is to fix with a slight push, without much lost by the object. By the way can be used without loss to the 3x zoom. The lenses have a 52mm screw and 67mm STUELP lid. For this price a recommendable Weitwinkelvorsatz, for shots in small rooms or groups.
