The lens is the new Canon EF 70-200mm f/2.8L IS II USM (Version II)

Brief samples after a couple of hours after receiving the Canon 1D mark IV. Check out "Photo Info" of each picture to get details about ISO setting and everything else. The video clip at the end was quickly put together and compressed by MPEG Streamclip to a 500mb file. It was shot in full auto and full manual mode using a fluid head tripod. The second video uses the same footage but edited with iMovie'09 and compressed using Quicktime on medium high compression. More to come, especially this weekend.
