Wow, the idiocy and ignorance of some of the comments on this forum are beyond the pale...I'm not sure I know where to start there's so much bull#%& here. But I'll take a shot at parsing it.
1) First of all, you're completely ignoring the segment of people who want to make photos AND videos and don't have $10-15k to spend on a true cinema camera. 2) Second, in a world where smartphone cameras are getting better and better and shooting better and better video, doesn't it make sense for an ILC to offer comparable video features to your latest smartphone? My thought is this is a pretty great marketing tool, otherwise Canon wouldn't have bothered to offer concessions like 4K in their latest cameras. 3) Third, what cameras do you think aspiring filmmakers buy before they become working professionals? They buy stills cameras that do video because they can use them for photos, too. Those beginning filmmakers start buying Sony cameras now...and graduate more often to FS7s, not to Cinema EOS. It's called creating a halo around your brand and getting buy in from an early age. Canon still has the most profits in the still camera industry but for those who are interested in video as well...they've lost quite a bit of resonance. I produce in New York City, and if a production is not shooting Arri, and not shooting RED, it's shooting Sony. 4) Fourth, just because you're insecure about video features in your photography camera doesn't mean you have to be completely ignorant and vitriolic in your comments about the features other people want in theirs. And 5) Fifth, just keep in mind that video is only 24 still frames per second- so in effect, your precious still photography camera just gets a much higher frame rate when video is implemented well.
I hope this clarifies things for you. You're welcome.
