I use it on a semi pro reflex, and I must say that the difference with my old cards SanDisk Extreme 3 is without comparison, for the following: - Time display of an image on screen or TV, - Waiting time to move from one image to another or TV, - Waiting time to display the mosaic of images on screen or TV, - Transfer time pictures to the PC, - Ability to take video clips as long as the housing support (with other cards, we go to the buffer of the device that eventually saturate) - Ability to take pictures in burst longer (8 frames / sec)
This is without comparison: the displays are snapshots on the new card!
