This was simultaneously shot with two Canon HD DSLRs using two very different Canon lenses. The 5D Mark 2 used a 24-70mm f/4 L wide angle lens for the distant shot, and the 7D used a 100-400mm f4.5/5.6 L telephoto for the up-close perspective. Since this video was shot in January, 2010 (which preceded the 5D2's 2.0.4 firmware update) both cameras were run at 30 fps. The audio was recorded separately with a Zoom H4N audio recorder which was placed in the foreground just outside of camera range. The split screen rendering was done in Adobe's Premiere Pro CS4 and sync'd with the H4N audio.
