I love 'em.

Me, too.  Especially yellow ones. Obviously.

Except for the im2500, I don't really use them for travel. But in a house with two toddlers, the protection during storage gives me some piece of mind (especially since they changed their former gaurantee statement to be proper and boring - the old one specifically excluded damage caused by shark bite, bear attack, and children under five - and no, I'm not kidding, it was on their website!).

That's great advice... my daughter is 4 and wants to play with Daddy's camera whenever she can get her hands on it!   Nice advice on putting the backpack into the pelican for travel... I will definitely be following your lead on that one, thanks.  I have a number of bags and most are Kata... very good quality although I don't think anyone else mentioned them.

Like Foveon technology the output of the sensor does not need demosaicing and instead of interpolating colour then de-bayering, the sensor has a separate red, green and blue photo site for each pixel – hence the 8MP count and the 1080p output.
That is, by definition, not Bayer interpolation, just like I wrote.

Right, but that is for the C300 sensor... they are binning an RGGB set and not using bayer interpolation.  But your assumption for the "red dot DSLR video camera" was that they were also going to use the same binning as the C300 which is why you then came up with the 50MP sensor (unless I misunderstood).  My point is that they won't use binning, rather they would capture a 4k image from the centre section of a ~17-18MP sensor (i.e. the 1DX sensor) and use the usual bayer interpolation to derive colour and luminance for each pixel.  This would differentiate the two cameras... the C 300 would only be a 2k output (from an 8MP sensor) but much better colour (they talked about getting better skin tones) and less noise than the 4k output of the new DSLR camera (from an 18MP FF sensor).

Anyway we're all just guessing here, who knows what they'll come up with.

The question is which 4K or is it actually QFHD instead?

http://en.wikipedia.org/wiki/4K_resolution

This could be a 50MP camera, Assuming 4:1 binning, Full Aperture 4K X 4 is 50.1MP, Academy 4K X 4 is 39.0MP, QFHD X4 is a mere 33.2MP and QFHD horizontal resolution X 2 with a 1.5:1 aspect ratio is 39.32MP.

My guess is the last value, but I still want to see if/how Canon handles viewfinder masking. I'm also a little puzzled why they would invent this new cinema body then stick their highest resolution sensor into a DSLR body instead.

Why do you assume binning?  That could be a difference between this new video-DSLR (capable of 4k but still Bayer interpolated) and the C 300 that only outputs 1080p but uses binning to increase image quality.

Assuming no line skipping and no binning, a 4k capture from an approximately APS-H sized crop mode (the press release noted "approximately 80% of the vertical and horizontal) would suggest the sensor is just under 17MP.  Given that they said "approximately" it could be the 17.9MP 1DX sensor.

Again, if you are going to claim this is f/2.8-3.5 you need to back it up because you're stating something that seems physically impossible - the lens having a smaller aperture than its T-stop rating permits.
Is that not how T-stop ratings work, T>f? ie DXOmark gives the EF 24 f/1.4 Lii a Tstop rating of 1.6, and the 17-55 f/2.8 has a T-stop of 3.4. At T2.95-3.7, I just guessed the new lens would have f/2.8-3.5, could be a lot wider aperture.
An "ideal" lens would have T=f, impossible is T<f? Or maybe i'm backwards, it's late.

I believe that's correct.  A T-stop can be measured for any lens, it is common for cine-lens where very precise control and consistency of the exposure is required.  For any lens, the T-stop is the equivalent f-stop if the lens had zero transmission loss.  Therefore the T-stop is always higher (larger number) than the f-stop of the lens.

At only 8.3MP for the FF sensor, if they've used all of their most recent tech with this sensor, then it should have very good DR.

Why do you think this concept DSLR video camera has an 8.3MP FF sensor.  The 8.3MP is the resolution of the Super35 size sensor in the C 300.

The layout of the sensor is 1920x1080x4 (RGBG)

Not quite.  The red and blue pixels are 1920x1080.  The green pixels are 1920x2160.   But ok, you could look at like 1920x1080x4.

Bornshooter was wrong about a 5D3 but they did announce the development of a new video DSLR... does he get even a little credit for that?   Nah, I guess not.

Since there was no 5D3 announcement I can now open the box to the 5D2 I bought last week  ;D  I probably would have either way.

I don't understand why the sensor would only record the size of an APS-H for video in 4k though.

Probably because the centre of the sensor (an area approximately APS-H size) is the exact number of pixels for 4K video recording without doing any line skipping or pixel binning.   They said approx. 80% so 4000/0.8=5000 and using 3:2 ratio that gives a 16.7MP FF sensor.  They said "approximately" so that could mean it's the 1DX sensor (18MP).

I agree that the 5D3 could be the bridge but I just don't see them announcing it today along side with it.
Well... But they HAVE to say something about this "phantom" camera on the picture... Canon wouldn't be so stupid to  publish such a photo without knowing exactly what they are doing... The phantom camera ist definitley PLACED there and not just "be" there by mistake.

Not sure about "stupid" but wow what a huge teaser if they don't even mention it!  Rumor boards will be abuzz until they address that second camera in the photos.

Very few replies here for an 'historic' Canon announcement!
Well, 16,000 bucks is a little bit out of my budghet...
Wait and see what the other camera costs.....

I'm more interested in the label on that second camera and am still hoping for a 5D3...

5D3 is not getting announced, this is a video only event. The 5D3 is a photography camera... not a camera entended for Hollywood.

You're probably right that it won't be a "5D3" but there could be a video optimized pro-level DSLR form factor camera announced.

Not that there is any rule that says Canon can't announce anything they want and could certainly add "one more thing" if they wanted to.

We're running a way a bit here.  Couldn't the DSLR picture just be of the 1D X with a purple 'C' badge on it, to show that you can use the new cinema EF lenses on a regular EOS stills camera?
I was thinking the same thing a bit ago.  Also, is there any significance to the RED color, indicating that this camera aspires to compete with RED equipment? Or is it just an additional notification of a professional body/lens combo?

Or the RED color could be because Canon's corporate color is RED.

The three primes are 24 f/1.5, 50 f/1.3, and 85 f/1.3.  It is interesting how the 50 and 85 are slower than the standard L series EF lenses, especially for such an expensive camera. They better be good.

No they are T/1.5 and T/1.3.  T Stops and F Stops are different.  I cant remember the exact difference, but I know that T stops let in more light, but T/1.3 is superior to f/1.2 for sure.
Oh dang. Well I feel stupid now.


Don't feel stupid, I would think they were the same too (and did at one point).

T-stop takes into account the transmission loss of the optical glass.  It is the equivalent of an f-stop for a lens that had zero transmission loss.

There it is on engaget... much clearer shot of the second camera and certainly looks like a DSLR with "C" badge in the upper left of the body.

Yup, it's gonna be the "but wait, there's more."  Not everyone is going to ditch their 5D2 for a $16k camera, it's too much to ask.  They're going to release something that they want to sell the S___ out of.  I'm willing to bet the primes will be around $3k or more/each

Next big question though... will it be a lower resolution sensor (i.e. less than 21MP) with the justification it's optimized for video?

Anyone else notice that the camera on the left in the group shot of all the new stuff is not the same as the C300 and it's NOT a 5D?  And has the same little light on it as the C300...Another cam on the way?

That'll be the 5D3... they'll announce it at the end as "oh, and just one more thing...".... woohoo bornshooter was right!!!

My thought exactly.  It looks like a standard DSLR; and they are going to say hey by the way we have the 5d-C have fun with that Nikon.

Or maybe it's a 1Dx.

I thought that as well and looked real hard at the "red light" to see if it was just a reflection but it really does look like the "C" on the C 300.
