Until I used my camera Pentax Kr SDHC card with a classic, but does not allow me to reach 6 frames / second which the device is capable. Yet it was a class 10 but the transfer speed was not following. It is quite another thing with this Lexar, which holds water and allows to reach full speed. Very useful for sports or animal picture. This card is perfect for my use. I recommend it, especially since its price is attractive. Very good quality / price ratio.
