I had the chance to test some SDHC and SDXC memory cards and SanDisk Extreme Pro is my personal favorite. Whether HD video from DSLR or fast continuous shooting; whether Canon, Nikon or another DSLR brand, the Extreme Pro simply shows a consistently good performance and well priced was able to convince the map. Clear the Extreme Pro is slightly more expensive than "normal" memory cards, but who often takes sequential shots and the data would have on your PC quickly, should here rather invest a little more. Along with the really robust construction "Memory card" for semi-professional and ambitious users.
