Well, I couldn't resist. I just picked up the Varifocal monster from Konica. I have a GH1, but I don't know if it's even safe to use on it. It'd be more like mounting the camera to the lens than vice versa.
Anybody here use this thing? I can find almost no info on it....
Wow. Got this monster in last night. I've gotta say, it's really a piece of art. The focusing and zooming are incredibly smooth, and it appears very sharp through the range (although all I did were some "HEY GIRLFRIEND! *FLASH*" shots last night)
If you hold it near the back of the lens it's actually pretty well balanced on the camera. Although I don't see this being used a lot without some kind of tripod situation.
