Canon USA has published a series of user guides for its flagship EOS-1D X full-frame DSLR, in the form of HD videos that are designed to be played-back on the camera's rear LCD. There are 18 topics covered, including a series of videos looking at how to get the best out of the AF system. Canon video tutorials are also available for the EOS-1D Mark IV, 5D Mark III, 5D Mark II, 7D and 60D. (From UnitedByPhotography, via CanonWatch)

Edit: in an earlier version of this news story we said the EOS-1D X was the first EOS camera to get a video tutorial. Videos for other models have been available for some time and the story has been corrected.
