I purchased this card from the perspective of power make animal pictures continuously with my EOS 7D.
I am fulfilled in this use can downtime between each burst and the write speed can not overflow the buffer of the device in two seconds.
I therefore strongly advice that any CF photographers seeking speed and robustness without breaking the bank.
For information, if you have not already taken advantage of the offer, it is possible to obtain a shockproof and waterproof case that can house four or eight SD CF by sending a scan of the invoice and a snapshot of the card in the packing to PNY.
