Canon EOS 6D In-Depth Review
Compared to Canon EOS 60D
The EOS 6D takes its design cues from the EOS 60D. In fact, there is very little in the way of body size, control layout and styling to differentiate the full frame model from its APS-C sibling.
Compared to Canon EOS 5D Mark III
The EOS 6D slots in below the 5D Mark III in the EOS lineup, and not surprisingly gives up some features in comparison. The 6D's much-simpler AF system is perhaps the most glaring difference, but it also shoots at a slower burst rate. However, 6D owners do get built-in Wi-Fi and GPS and interchangeable focusing screens.
Compared to Nikon D600
The EOS 6D's most direct competitor is, of course, the Nikon D600. The cameras share similar dimensions but differ significantly in control layout.
