"we have so many choices and as a Director we simply have to make a choice, is it the right choice? Why yes it is, because without taking responsibility, there is no creativity."
Sorry, I missed the part about the external recorders. I've never personally used a recorder with the C100's. It's possible that with an external recorder a C100 could match a C300 in image quality. The numbers would seem to add up that way. I will say that having those kinds of peripherals on the camera can be a real pain in the butt, though. I'll always opt for a more simple-to-use solution if I can. So I might still lean toward the C300 (as long as you don't need slow motion!).
All of those cameras are really great. Having used each one, I can say that there is a noticeable difference in IQ between the C100's and the C300. Even though they both have roughly the same DR, the colors are more robust and more nuanced in the C300, and it stands up to grading better. It's probably not something most people would be able to see, but I can tell. You'll have to weight he cost/benefit of that I guess.
At this point I would buy whichever one you choose used. The new prices are ridiculous for the market we live in today, and Canons are reliable workhorses so you can worry less about any issues with a used unit. If you plan to shoot any slow motion, your obvious choice is the C100 II, as it's the only one that can shoot 1080p at 50/60fps. If you don't plan to shoot slow motion, I really might go with the C300. It's just more of a proper camera.
At this point, I wouldn't recommend buying a C100 MkI. The lack of slow motion AND the poor functionality of the EVF, non-articulable LCD, and lack of camera control on the body (only joystick on the side grip :P) make it a pain to use compared to the other two cameras. It's also reaching the extreme end of its life in the market.
I think someone said on the forums that both cameras had the Low-light OLPF's in.
Frank/Ninjamonkey. Only a fool attributes his failure to others. Seriously man, invest in a business coach. It sounds like you could use it.
Funny. Resolution aside, I actually thought the colors in this were the best colors I've ever seen out of a Red camera (and I really don't care one way or the other). The skin tones felt much more accurate than MX or Dragon, and the blues and reds felt deeper, very Alexa-like.
I also found it interesting that the image was so clean. I don't know anything about the lighting they used or the exposure, but I expected Helium to really struggle with noise--in this video it definitely did not. Though again, I don't know anything about the lighting conditions.
Anyway, I guess I've always been on your side of the fence: who cares about more resolution? The Helium felt silly when it was "announced." But having seen this, I have to say I'm excited to see more. It seems like another step toward full maturity for Red, and I'm always a big advocate for as many good options as possible when it comes to tools.
