Having a WA lens as standard, what options do Pan users have in gathering tele footage with the 72mm threaded stock lens? From conventional to non-conventional- inquiring minds wanna know!!

Century Optics makes a 1.6X extender. Expensive though.

1.6X hmmm that would likely put it near the 14X / 16X optical of the other DV cams- anyone know of anything more powerful- say 3X - 5X ? How bad do you guys think the Kenko 5X extender would vignette with it's 37mm lens (we'd have to use a 72-37mm step-down ring to get it on) but how badly would this vignette?

If this works a DVC80 will be mine within a few days...someone please tell me this will work!
