Canon USA has published a series of user guides for its flagship EOS-1D X full-frame DSLR. However, rather than the conventional PDFs it offered for previous cameras, this time it has created a series of HD videos 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. It’s an interesting idea and one we suspect we’ll see again.
