My first "serious" digital camera was an S1 IS, and I bought the Wide Angle (0.7x) and Tele (1.6x) Converter for it. Anyway, it's a 52mm thread and fits on my macro lens. So, it should fit onto other 52mm lenses w/o a problem. I wonder how the images will turn out. Turns the 60mm into a 42mm lens with the WA converter, and a 96mm lens with the Tele.
I'll try to mess around with it tomorrow.
