One of the features I really like about the Canon 7D Mark II is its 1.6x crop factor when coupled with a 1000mm lens combo set up (500 + 2x). This Northern Shoveler and several other species were not too far away, but far enough that I probably wouldn’t have bothered even attempting to photograph them with my full-frame body. But actually, the jury is still out for me as to the comparison between the 5DMarkIII’s full-frame overall higher quality image-making capabilities and the 7DMarkII’s ability to better fill the frame while shooting, possibly even increasing focus accuracy because of it. (There are many other technical factors that come into play in this comparison besides the few I mentioned). The effective focal length of this shot is 1600mm (1000 x 1.6 crop factor). At some point in the future I will do some test shots in the field on a stationary subject with both camera bodies just to satisfy my own curiosity.
