EOS 7D Mark II Spec List Surfaces [CR1]

...and people keep saying that they are the same auto focus system but they are not.

Actually, they are the same in terms of components - same sensor, same dedicated AF processor. As I stated above, your statement that the 5DIII lacks a dedicated AF processor is incorret. The difference is the metering system of the 1D X feeds data into the AF system to allow for face recognition and tracking (although Canon warns that using iTR may slow down AF).

Simply enough, the 5D MkIII is certainly not the 1Dx... Never will be but it's a fine piece of equipment in and of it's own right... I love mine. I have room enough in my heart to love a 1Dx too! ;D

I still think single SD or CF card could cause a bottleneck in the data pipepline. If you do the calculations you'll see that 24MP at 10fps is a higher data rate than the 1DX so I doubt it will actually be that much. It is more likely to be around 23.3MP (like 5D-III) and 9fps, which would still be an improvement on the 7D. Those numbers at least seem to be inline with the capability of the dual-digic5+ architecture as seen in the 1DX.

If you have a 95mbps SD card and the slot/chipset supports full speed 95mbps then single SD slot should be no problem. If an older tech slot/controller on the camera is used then it may be.

i.e. one of these:

I just down loaded some CF cards and I sustained 102MB/sec bytes not bits. That's just more than 8 times your 95mbps SD cards.... Can we just stick to the better cards please.

SD where meant to be smaller and cheaper than CF

You can't really use the number of frames per second or the number of megapixels to argue if the slot is SD or CF without considering the buffer size. Nothing states how many shots before the buffer fills or what the size of the buffer is. Make the buffer bigger and you can live a lot longer with a slower storage card...

If you want to run continuous, assuming 32Mbyte per raw image and 12FPS, you are looking at 384MBytes/sec sustained transfer speed.... that's 32 times the speed of your 95Mbit/sec SC card or 6 times the speed of a 160Mbyte/second Sandisk Extreme Pro CF card. ( Read speed is 160MB/sec, write speed is 65MB/sec). Whatever technology they put in the 7D2 for card slot, it is the buffer size that has the most impact.....

If you assumed a 2 second burst and a buffer big enough to hold 2 seconds at 12FPS:
SD - 25 frames and 64 seconds to clear it
CF - 29 frames and 12 seconds to clear it

Does anyone really think that Canon would make a semi-pro camera that can sit there for over a minute trying to clear the buffer? The smart money is on CF.

don great info, but really there is nothing from stopping them from putting 2GB or more in for buffer really that's what I think it should be min.

Hi Don, Thanks for correcting me on number of cards and valuable info on buffer size.

I can be quite lengthy in my replies sometimes and browser ends up timing-out, so I type responses in text editor and cut+paste into the forum. Sometimes I try to rearrange sentences and fail horribly. The first line my paragraph has nothing to do with rest of the paragraph. The rest of the paragraph is discussing DD5+ capability and the shooting speed of the rumored 7D-II it has nothing to do with number of cards. Apologies.
