I finished this video about 2 weeks ago and was interested in what you guys thought. I don't remember the lens used as my DP used a few different kinds but it was an interesting shoot as the first half of the day was incredibly cold, windy, rainy, and had little to no sunlight. The 2nd half of the day cleared up a lot but the 7D was still pretty resilient. Enjoy
