Any ideas on pricing yet??  Are we talking $5K, 8K??  Or less?  Hoping it's not insanely priced!

The video frame rates are way too crazy. Nobody would want such a varied of frame rates based on the Crop. I don't think Canon would do something that dumb, so yeah... probably someone with too much time.

The math is wrong on this spec list.

A 32.4MP sensor means ~7000 x 4666.

The 1.3x and 1.6x crop factor applies to the width and height *individually*.  So, for example, the resolution in APS-H mode would have to be:
7000/1.3 x 4666/1.3 = 5384 x 3590 = ~19.3MP

And in APS-C mode would have to be:
7000/1.6 x 4666/1.6 = 4375 x 2916 = ~12.8MP

Also, the viewfinder calculations are off:
APS-H viewfinder: 59% of full-frame viewfinder image
APS-C viewfinder: 39% of full-frame viewfinder image

i'm sooo glad i only take photos with my cameras - this thread requires a doctorate just to keep tabs with the science!

Of the options being touted for a new body release, i personally would prefer a 1D5, but suppose 1 Ds4 wouldn't be to unwelcome.

As for what the specs are, we'll not really know until it is released. Given that a 5D2 can handle 21mp with a single Digic 4, i'm sure that 32mp is not too far off for next MP rating, working ISO would more than likely push to 25k or 51k and video - who knows. Having spoken to a person who teaches video at a college, he was more than keen to extol the virtues of DSLR's over full blown pro grade video kit where price is concerned. Tell me Canon haven't worked that one out as well?

Besides the sensor math being wrong, this whole list of specs seems rather nonsensical.

The described camera seems guaranteed to disappoint everyone. A bunch of half-measures and nothing that would be considered game-changing.

I have more confidence in Canon that after all this time, when they finally release a new flagship, they know it must be nothing short of awesome. These specs are frankly a little boring.

This raises a question I've been wanting to ask for quite some time. What exactly constitutes a Canon Rumors source? Not being critical of Canon Rumors Guy, but just wondering. If I make up a bunch of specs and send an email that says I have access to inside information and these are the latest specs for the new Canon 8D Mark VIII, do I become a CR1 source? Do I have to substantiate anything or what?

It's Canon Rumors Guy's website and I appreciate that. Just wondering though what exactly a "source" is.

Do I gather that this possible EOS will have the option of changeably using 1 of 3 sensors? Or that it is to be bought with one of the 3 sensors? If the former, then this does in fact seem to be an impressive game-changer, as the studio-oriented user could generate huge files, and the spot-news shooter could generate much smaller files, but at 10 FPS ... is this possible understanding correct? Does anyone have a guesstimate of a price? I would surmise upwards of 7K ...

It's not hard to understand. You don't need 3 sensors...

Option 1 : Sensor start at 32mp and 5fps. If you want to sacrifice resolution for speed you pixel-bind, like shooting sRAW files and output 12mp images with 10fps.

Option 2 : Sensor also start with 32mp and 5fps. If you want more speed you read only a part of the sensor (think APS-C, 1.6x crop) in the center. Since you have less resolution you can go faster.

The Option 2 technology is not something Canon has shown to be possible yet. But Option 1 is. Canon produce sRAW images by binding pixel and also does create 1080p video frame at 30fps using the complete sensor. So Canon CAN read a full sensor faster when using lower resolution.

Pixel size about at the limit for optics.

Frame rate can be adjusted at the expense of picture size for action shots.

APS-H mode so everything looks just the same as what you've been doing the last 10 years.

Video at 100fps to get great slo-mo....

Sounds like the ideal sports photographer camera - maybe the ideal 35mm camera.

I want one. How much?

The formats do not make sense.  If the sensor is 32MP at FF, cropping the image electronically would yield just less than 19MP at 1.3 crop, and 12.5MP at 1.6 crop. 

"Pixel size about at the limit for optics." has been said about every DSLR for the past 5 years.  And what optics? An L prime at it's best settings? or a consumer zoom?  Or are those the same?

So? 19mp with a 1.3 crop is better than the current 1DIV resolution. Double Digic V would most probably be able to handle this at 10 fps. You get to trade speed for resolution depending of the job to complete.

Sorry, I don't buy this idea of a ff /1.3 / 1.6 switching idea.

Apart from making the viewfinder behave erratically, it would move the AF sensor points all over the frame so that you'd have to have a far more complex AF system too. Above everything else, a pro-camera needs to be reliable. Complexity and reliability make uncomfortable bedfellows.

I can however believe that maybe they have implemented on-chip binning modes so that the camera will output a 2x2 binned image, or a 3x3. Doing this (theoretically) gets you 2 and 3 stops of dynamic range respectively. CCD cameras used in astrophotography have done this for years - it's time that the DSLR caught up. Importantly, it reduces the amount of data that the chip has to shift so that frame rates go up.

As for video... um.... who cares? Neat for a semi-pro but Canon has professional video cameras.

This is fairly inline with what we’ve heard previously.


If you take a FF 32.4 MP sensor and run it in a hypothetical 'APS-C mode' you don't get a 32.4 ÷ 1.6 = 20.3 MP image.  The 'crop factor' is a diagonal measure that impacts field of view, but real pixels on a sensor have both x and y dimensions, so when you scale a FF 32.4 MP sensor to that 'APS-C mode' you get a 32.4 ÷ 1.62 = 12.6 MP image.

Please, go waste someone else's time, or come back when you're smarter.

I declare shennigans!!

Agreed, this one deserves a CR0, I think.

this is just a silly copy of the post last week that had the same totally wrong math in it that came up with nonsense MP crops

Sew buttons.  It shows this spec list is nonsense.  Nothing wrong with the concept, Nikon did it with one of the D2s as I recall, but assuming the pixels are the same size throughout the sensor, the numbers in this spec sheet are sheer comedy.
