Check the channel "Lost Lakes" on YouTube. Jon's got an episode where he discusses his camera gear, which currently includes an S5 and an S5II along with a modest arsenal of LUMIX and Sigma lenses. I know he's shooting the Sigma 100-400 zoom, along with I *think* the 50mm 1.8 prime. Jon used to work at Black's Camera in Toronto, which is where he developed his chops.
In my not-at-all-humble opinion, it's one of the best looking, most cinematic channels on YouTube. But then again, I've got a weakness for wilderness canoe-tripping.
