"...Shot on a 5D Mark II and EF 17-40 Lens, on Toronto Island Ferry. February 2009..."

It says inside the Video Description. It's ferry that did the "panning" ;)

I just have a hard time believing a ferry could be as smooth as a Steadicam.

Why? Water surface is perfectly calm (well, it's under some heavy, although cracked ice), it's not like it was sitting on some huge waves or something. All you need in situations like this, is your ferry gliding... just like glidecam, LOL.

What I do believe is that he also used some kind of post-processing to emphasize steadiness even more (even iMovie '09 does it... AfterEffects, Final Cut Pro etc.).

Also, since I am pretty sure 5D can not record in 60fps (this is just too smooth to be 24 or 29 fps), I do believe he used one of those frame blending methods in AE. There is one called "Frame Mix" and another even more precise, and of course a lot slower to process, called "Pixel Motion". I always get super smooth footage with 60fps on my Canon 7D, especially can be noticed when I slow it down to 29.97 fps at 200% time stretch, but on 5D you would have to do it in post-processing to achieve it.

Also... the big part in all this plays his wide angle lens.

Yes you pretty much said it all. Ferry ride on ice is pretty smooth, and I imported the footage (29.97fps made from 30fps from camera using NeoScene) to After Effects and change the speed to 50% using TimeWarp in Pixel Motion method.

Sam, this looks epic! And the other one called "No swimming allowed"... However, I have to admit I am not a fan of the video where you were biking through the city without using your hands. We all know how many car/bike accidents ended up in Tdot, and for sure we don't need another one. It's just too dangerous. Save your and other people's life by riding safe. Every single life on this planet is too precious to play with it.
