One of the reasons i've always wanted a DVX100, is that its the only camera with a wider fisheye available for it than the VX1000 (my current camera). I was a little disappointed that there weren't that wide of fisheyes available for the HVX200 (which i've been planning to get). The DVX100 and the HPX170 are both 72mm right? So would the bayonet mount be the same size as well? Would i be able to mount a DVX100 .3x Century Optics fisheye to the HPX170 and use it for 4:3 shooting?
