I was at the Hall's Gap (western Vic) zoo and a group of Americans arrived to film the zoo's white kangaroos. While one bloke had a regular video camera, another was shooting stills, but this particular character wandered around with this Canon 5D attached to a large, curved metal "handpiece thing"
1- here he is...
2- here hs is again, 1/2 hidden bu the mic & zoom lens of the video camera
All guesses are acceptable
