after thinking about all this a bit, the canon makes some sense...
the only reason to go with red (any of them) is the option of raw video, which provides still shooters (like most people here) in a commercial/advertising/fashion field with raw still frames of the video footage shot....like cooter says, scrub through the footage and pick a frame...makes a lot of sense for some of us....
the c300 goes in a different direction....most TV, movie, documentary, tv commercial,...production could not care less about raw or still frames....they want super clean, higher iso (keeps production costs down), maybe 60 or 120fps...all in great looking HD....that is why most DPs LOOOOOVE the alexa....when you are shooting with 4 people hovering around the camera it really does not matter how much the camera rents for....
i think the c300 goes right up against the alexa....no AF, super clean, sharp HD with accurate color....at a very reasonable price...the only issue might be the frame rate...
the scarlet is somewhere completely different, it does many more things and probably/maybe, in the end since it all ends up in HD anyway, the c300 (or alexa ) footage looks better....maybe...
the one thing about the scarlet is that in order to get the full size of the sensor it has to be shot at 5k which only does 12fps....at 4k it is already cropping into the sensor, at 2k 60fps we are looking at a 16mm camera.....something to consider....
so in order to really use the sensor, get video (not 12fps) and to get the raw stills the ad wants, 4k 30fps is the only want to shoot the scarlet....which eats up storage...
laforet mentioned that they shot the entire film with 2 c300 on a 500gb hard drive....that is also something to consider....
in the end there still is no perfect camera for all....i am still not sure canon priced the c300 right...but i would not have bought it for half of the price...for me the raw frames make the red the only game in town....and for someone lusting after the alexa the c300 might deliver at less then a 3rd of the price....
one thing is for sure....canon is in this for the long haul and they are selling enough other stuff to keep this little project alive for a long time....
and as soon as they figure out a way to pull 24 shots/sec raw off a dslr sensor red is toast....the 1dx does 18fps? (on a 35mm sensor) that is 50% more then the scarlet at 5k.....
i don't see why the announced/unannounced c-dslr should not do 24fps on a smaller sensor....
the one thing that blows my mind is that the same week hasselblad announces their new body without sensor, same look, no new features...for 7000$...who buys this stuff anymore?
