Why is the c 300 sensor is not Full Frame (24 x 36 mm)?

[ssrdd]

''The EOS C300 conforms to the industry standard Super 35mm Motion Picture Film frame size. Almost all PL Mount motion picture lenses are designed to cover Super 35-size film or digital sensors, and tend to vignette heavily on Full Frame sensors since they are not designed to cover that frame size. The EOS C300 PL is compatible with all PL mount cinema lenses that were manufactured with Super 35mm in mind, allowing the cinematographer to match the same angle-of-view as when working with a motion picture film camera.''

So the canon should have made two versions EF with full frame, PL with the conventional format. then we would have an option about the people who invested in canon pro lenses and used to the full frame depth of field.

Two bodies with differing mounts & sensors has extra costs, from development, through stocking, to bug fixes (read: firmware updates).

Having one body that works with both types of lenses has some advantages, e.g. allowing the use of special lenses (macro, super tele, tilt-shift) on cine cameras, or allowing people to start with cheaper EF lenses.

all movie cameras are super-35 (even the very expensive ones, like RED, alexa, F65); that's the movie standard, that's what moviemakes want

there's been a lot of "if it's 1080p I won't use it, I want at least 4K" and also some "if it's 422-8bit I won't use it, I want at least 422-10bit"; I haven't seen anybody complain that it's not "full frame"

among other things, because what you call "full frame" is what movie people call "vistavision", and it has hardly ever been used; if it could be had for free and with no side-effects on S35 capture, moviemakers could live with the larger sensor as an extra goodie, but their beloved glass won't work on that

they're much more interested in dynamic range and codec strength

Well, I suppose from Canon's development team for the C300, 'full frame' isn't exactly a movie look. On the 5D it looks better when you crop the image if you're going for the movie image. Naturally the advantage of the full frame is that you have more leeway to manipulate the footage in post, but if you're good at getting it in camera then it shouldn't matter. Who knows, 3-years from now they might develop a C300 mark 2 with a full frame sensor.

This is why the PL mount glass works on the 7D crop sensor rather on the full frame 5D.

What exactly do you mean "not exactly a movie look? I have a few 5DII's and I don't ever "crop the image going for a movie image?" You mean adding a letterbox to the footage? People just do that to mimic the look of anamorphic stuff.

And a full frame sensor doesn't give you anymore leeway to manipulate the footage in post, higher resolution does \. I can crop into a 5D or 7D shot the same amount (about 112-114%), but since it's 1080p it's gonna look crappy/pixelated if I go any higher. That's the whole point of 4K footage right now, you can create artificial movement in post without hurting the image quality too much. Do a little research, it sounds like you just read things here and there on the internet and dont have much actual experience.

It's personal preference. If you want a more dynamic look to the footage I wouldn't keep it at 1920x1080.

I wasn't referring to resolution, I was referring to the area of coverage. I have a 5d and have shot video on the T1i, I really don't care for a cropped sensor as it doesn't allow me the same area of coverage of a subject while maintaining a certain depth of field. On a cropped sensor you have to pull back and lose DOF to get the same scene a full frame is capable of. BTW, take a look at my profile picture, that's my video set up.

Im not sure the OP understands the difference between Video and Photography frame sizes.

Heres a simple Graphic:

You can see that the Super 35 Film is actually slightly smaller than APS-H Photo and well under 35mm Full Frame.

Its one of the problems when trying to take photography terminology and applying it to video/film specs.

If you look at this one from RED you can see the differences in video terminology. Remember 1080 is only usually around 2MP whereas the C300 is shooting at 8MP.
