In the 7D, not the EOS-1D Mark IV The EOS-1D Mark IV is meant to be a better-specified camera than the 7D in most respects, and ought to be, given the much higher price tag on the camera being unveiled today. That said, the 7D incorporates several features that didn't make it into the EOS-1D Mark IV, features that would be equally useful in Canon's latest news and sports camera.
These include the 7D's combo mode switch and start/button, Q button for quick access to key camera settings, unparalleled control customization options, an electronic level and revised 63-zone meter. The lack of some of these refinements gives the EOS-1D Mark IV the feel of an interim product, like an EOS-1D Mark III N. That said, if the autofocus and high ISO image quality are top-notch, then the absence of things like an electronic level won't keep the EOS-1D Mark IV from flying off store shelves.
