Oh dear, this is soooo gone wrong.
In the first place, 1Dc, C100, C300, C500...and now even XC10 and 5Dc WTF?!?!?!?
And then they make 5Ds, 5DsR, 5Dmk4, 5Dc?!?!?! Is this a comedy? Where are the hidden cameras? Coz this must not be for real.
OK Canon, here is what you will do: just cut the crap and
- make 5Ds and 5DsR into ONE product (as Nikon already figured this is better)
- make 5Dmk4 and 5Dc into ONE product, a 28MP real low-light performer camera with advanced video features
- forget 1Dc and C100
- make C300 and C500 into ONE product
- make XC10 as small and versatile as possible and make every 3rd party manufacturer support like hell so it becomes a de facto camera for anyone who is wishing for something more advanced than a gopro for action, drone, underwater and every possible special application
And you know you can keep the billions of dollars this advice has saved you, I just want to love you again like in the old times before you started bullshitting

((((
Oh by the way, what about previous 1Ds users?!?!? You abandoned all of them. The people who bought your most expensive camera, mostly professionals, were left behind! They spent shitloads of money on a camera for a reason. They needed resolution AND the features of EOS 1 body. After 7.5 years they still do not have a proper upgrade!!! They either have to give up resolution or the famous EOS 1 body. WTF again?!?!?
So you get that 50MP sensor (or one that is at least around 35-40MP) and put it in a EOS 1 body, name it 1D Xs or whatever! Make a damn flagship camera because currently you do NOT have one! Just make a camera that is the wet dream of every photographer and then you are free to price it whereever you want, $6000, $7000, $8000? It doesn't matter because it's worth it if someone can pay that price. And let's admit, most professionals who really make their living in photography will not care either, just as 1Ds was widely purchased despite the price. Beacuse that and only that was THE professional camera (and later 1D also).
Your professional camera has 18MP and the prosumer camera has 50MP

))) I'm still searching for the hidden cameras, I'm sure I'm in some kind of joking show.
