Canon today announced the 1D X Mark II, its latest flagship DSLR. Canon calls the camera a "remarkable combination of innovation and refinement" that
One of the interesting new features in the 1D X is built-in image optimization. Canon’s new Digital Lens Optimizer technology stores information about the optical flaws of lenses and then digitally fixes those things on the fly with virtually zero decrease in camera speed. For the first time in a Canon EOS DSLR, the camera can automatically correct for peripheral brightness, chromatic aberration, distortion (barrel and pincushion), and diffraction (blurring at small apertures) — things that were previously corrected in post-production.
It’s very compact due to the sensor being smaller and the omission of a mirror box. It has full manual controls for ISO. You can change the shutter and iris manually WHILST filming, no exposure lock needed. It has an autofocus that works pretty well whilst recording, both in centre frame mode and using facial recognition mode, something I have recently found outstanding on the little Canon VIXIA HF20. The ability to have full manual controls should not be underestimated. At the click of the dial on the front you can switch between aperture and iris. This can be done whilst shooting.
