Has anyone tried the Panasonic DMW-GCK1 conversion lens kit? Panasonic DMW-GCK1 Conversion Lens Kit DMC-GCK1 It looks like they have the macro and wide angle converters plus a fisheye converter in a single package (but not the awful teleconverter) for $319. That's a better deal than getting them separately, but is it worth it? For a bit more you could get the Samyang 7.5 plus a legacy MF macro lens (or just a reversal ring for even less). Could software correct the fisheye effect on the Samyang if you just wanted a standard wide angle shot?
