I am still on my Alaskan photo shoot. Down in SE Alaska now for some whale photography. Brought with me the Canon EOS-1D X, Mk IV, EOS-7D bodies plus the EF 200-400mm and EF 100-400mm lenses.
The EOS-7D is my favorite APS-C camera for wildlife photography. The EOS-7D Mk II should be coming out at the end of the first week of September. In fact, Amazon has already stopped carrying the camera on their website. It seems they have drawn down their inventory of 7Ds to zero.
I am quite enamored of the EOS-7D's performance as a cropped frame camera provided the light is good and high ISO is not required. The Achilles heel of the camera is its mediocre ISO performance but the Mk II will address that 'weakness.'
