I already owned a Sandisk ultra 32Gb SD card, which i had been using for 2 years on my 550D, so felt to give a try when i upgraded to 5Diii. This card is amazing for using the near full potential of your camera, though i never use 6fps which is for 5D mark iii i.e 6 shots of 25-30mb each, will require a write speed of 150-180Mbps, which is near impossible. This card can stand 4-5 shots per second without any lag. I bought this card mainly for videography. Here i would rate it full stars, never encountered video stoppage due to speed of the card unlike the Sandisk 32Gb 30mbs ultra SD card, So this is a must buy for those who have a CF card slot in your camera. Also if you dont have a CF card reader, use your camera cable to copy the photos to your Hard drive. This is a little slow process compartiviely.
