Konica Minolta Diamge Z6 Image

[wizcam]

I have the Konica Minolta Diamge Z6 Image and the wide angle lens and adapter. I purchased the Canon TC-DC52 52mm 2.4x Teleconverter Lens. It seems that when I use it only the center of the picture will come in focus. Am I doing something wrong? Did I get a Lens that is not compatable with my Camera. I have The Canon TC-DC52 screwed onto the wide angle adapter without the wide angle lens, No filter in between. SHould I Return this lens and get another? Does anyone know which lens would work?

Thanks

Stan
