I've read a blogpost from Jeff Cable Photography, a fellow photographer that uses a Canon EOS 5D Mark III, who found out a slight issue with the 5D Mark III SD slot which gives a slow buffering when using both the CF slot and SD card both altogether. But i think this will not be an issue for those who don't really care for memory card speed. It is said that the 5D Mark III has a max of 133X speed of SD card so meaning that even if you have a 600x speed SD Card or 1000X it will still buffer at the speed of 133x. The only speed that you will get is only when you are transferring the pictures into your pc, or macbook.
Considering that it is a limitation of the hardware, this problem can't be solved even if there is a firmware upgrade which is quite a bummer for Canonians that uses 5D Mark III. But hey it's not really a problem right because you still have the CF Slot. Even the Lexar Card that supports UHS which stands for Ultra High Speed where the Lexar has 1000x speed is still very fast and you can take advantage of this.
Here's from Jeff himself,
Well…after some testing I have determined that, if you care at all about high speed shooting or clearing you buffer quickly, YOU DO NOT want to put a card in the SD slot. Why? Because, for some reason unbeknownst to me, Canon decided to build the 5D Mark III with one very fast CF slot which supports the newer UDMA7 protocol and a standard SD card slot which does NOT support the high speed standard (called UHS – for Ultra High Speed).
Canon EOS 5D Mark III Overview Canon EOS 5D Mark III is the latest model in the Canon's line-up for FF full frame DSLR following the previous Canon EOS 5D Mark II which is known for it's first HD capable DSLR in the market. But today, Canon has updated it with a much better upgrades for the HD monster camera with a few nits and picks that will surely make all the videographers in the world smile everytime they dream of this camera. :P I think Canon did a god job in hearing the customer's feedback from the previous model and made it happen to improve the camera as this made the difference between this camera and other HD DSLR in the market. As more and more photographer's also incorporate videos in their jobs such as wedding jobs and other assignments, this will surely cater the needs of photographer and videographer enthusiasts. We are now seeing more creative directors turning their vision into reality through this camera and I'm sure many will be inspired through the works that have been featured.
In-Depth Review
Features of this camera:
22MP full frame CMOS sensor
ISO 100-25600 standard, 50-102,800 expanded
6 fps continuous shooting
Shutter rated to 150,000 frames
1080p30s video recording, stereo sound via external mic
61 point AF system
63 zone iFCL metering system
100% viewfinder coverage
1040k dot 3:2 LCD
Dual card slots for CF and SD
With the 22MP full frame CMOS Sensor, how will it benefits to the photographers? This will surely be anticipated for photographers who are seeking for higher resolution photos that is very useful in post processing, and printing in large sizes. Having a large pixels is always better for commercial photography but for home-use I don't see this as a problem. Even a camera with a pixel of 5-10 MP is more than enough if you were to just print the photo is 3r sizes.
Canon also claims that the ISO for this camera ranges from 100 -25 600 and expandable to 102,800 but I think it will not be useful even in low light condition as the grain will spoil the images. But at least you can get some images in super dark areas. Sometimes the message in the photo is more important than the quality. I repeat, sometimes.
With 6 fps this should be sufficient for sports photographers that want to get cool shot like those who are taking shots in sports like skateboarding, football etc. I guess most sport's photograper needed higher fps so that they won't miss any important moments. In addition, the shutter is rated at 150,00 frames before you ca change or service the shutter frames. If you always keep ons hooting on burst mode, this no will be achieved at a short period of time.
The camera also has 1080p 30s video recording system which will appear interesting for videographers and directors. It also has external mic if you wanted to choose to use higher end microphone like rhode mic which delivers superior sound quality compared to the original mic.
With 61 point AF system, autofocusing in a low light condition will be as easy as eating peanuts. You can also have a greater control on where you want to have the camera focus especially if you want to do close-up shots or macro photography. With 100% view coverage, you will have an ease of viewing through the viewfinder and get 100% image just like what you see in the viewfinder. The viewing of still images and video that you take will be much clearer as Canon decided to put a 1024 k screen resolution which will deliver superb quality and the image displayed will be more detailed.
I'd also like to point that it also have dual card slot for CF ans SD card so this is a big advantage to most photographers. This is because you can choose either to backup your image on the 2nd memory card on the fly, or choose to shoot RAW files on the other camera an the other one is set to jpeg files. Which will save a lot of time when converting them later on. This will also be helpful if you are taking sensitive images and the officials ask you to give them the memory card and they won't notice that you have another memory card that has the same image that they want to confiscate. Pretty gnarly right?

Don't follow that face while viewing through the viewfinder guys. ;P
If you have the same mindset as me, i'd go for video HD Capabilities DSLR. Perhaps this one can be a good contender for the bigger brother, canon 5d mark iii? let's see how it goes.
