New rumors on the Canon 7D Mark II point to an integrated battery grip for vertical orientation shooting, which would point the APS-C camera squarely at pro shooters. Part of the speculated reasoning behind such a move is to make room for a bigger and more serious battery.
As noted by Chuck Westfall, “the EOS-1D X achieves a higher lens motor drive speed with select L-series USM telephoto lenses than the 5D Mark III because of the 1D X’s more powerful battery pack.” Accordingly, the bigger battery in the rumored 7D Mark II would give it more punch with the larger L-series telephoto lenses.
These rumors make me feel even better about my prior speculation on where the rumored upcoming 70D fits in relation to the 7D Mark II. If the 70D goes back to the build quality of the 50D and prior models (as opposed the more plastic and smaller construction of the 60D), then the 7D Mark II would make a lot of sense as a pro-level APS-C shooter (or “Baby 1D X”).
Rumors continue to point to a late-summer announcement for the 7D Mark II.
