SD card for 5d mk iii
« on: May 19, 2012, 06:13:30 PM »
Im planning to get a Sandisk 32gb 90mbps CF card. I wanna pair it up with a 32gb SD card. I dont know which one to get the 45 or 95 mbps. I read here somewhere that the SD slot of the 5d MK iii is slower than the CF and if i use a 95mbps card I will only be able to use it at 45mbps. Is this true? Which one did you guys choose to use for your camera?

The 45mbps will be fine in my opinion. I honestly use the SD card for back up storage when the cf fills up and or Jpeg write only.  SD speed isn't too much of an issue for me anyways I don't think the 5d mark iii can read and write at  95mbps unless canon allows it with a firmware upgrade.

Its not that the SD slot is slow, the issue is that it does not take advantage of the speed offered by UHS-1.  So, if you buy a UHS-1 card, it will fall back to class 10, and you have paid for a speed you will not get or use.  The referenced card is 45 mb/sec when you have a UHS-1 compatible camera, but much slower with a 5D MK III. 
 
The card will fall back to a 30mb/sec, and basically operate like this card, so you paid extra for speed you will not get.
