People on this forum may not like the fact that canon mix video with their stills cameras, branch out into higher end video cameras for the movie industry and now are moving into security devices. But such moves are intended to keep the company growing, or at least reduce the losses from other lines of business so they can still make lenses and cameras we are interested in.
Security devices is a low margin, ridiculously competitive market. There's no money for Canon there.
Movie making? Really?
High end is dominated by Panavision, Sony and RED.
ENG/Documentary is Sony, Panasonic
Low End/Event/Budget is Sony, any DSLR and Panasonic.
The Canon cinema cameras so far have been over priced under performers with "me too" features and firmware crippled bodies. Too expensive for the causal/student/prosumer/low budget shooter and too low end in resolution, features and cross compatibility to compete at the high end.
Canon thinks too much like a DSLR camera maker to compete well in new markets. There systems are closed, filled with proprietary technology and standards, and the bodies and lenses are crippled by stripped down firmware.
Contrast that with Sony, RED or Panavision's high end gear. They give you access to all the features the hardware is capable of, make sure the gear is compatible with everybody's add-ons and go out of their way to make sure the post production path works with everyone's software almost from day one. And Canon's have no clear upgrade paths to better sensors without replacing the entire body - unlike Red, Panavision, and others.
In the mean time, Canon's flagship camera business, the DSLR is floundering. Way to tank your entire business.
