This video reveals my  first impressions after using the 7d Mark II for a few weeks.  I found the focusing system and ISO performance to be huge improvements over the original 7D.  For the sake of wildlife photography, I really think that the 7D has really overtaken the 5D mark III.  The frames per second, and focusing system really give it an edge, now that its ISO performance isn't lagging as far behind the full frame cameras on the market.  I will add links to where the lens and camera can be both bought and rented below.  Here are some images I captured with the 7d mark II with the 100-400 L version II
