(out of topic) Funnily enough it happens just after the two of three runs of the skiers. That means there was only one run left, and then the fog... was threatening and the 3rd run had maybe to be cancelled. It all went fine after all, they did the 3rd run and my old Extreme III did not too bad with the speedy FPS of the 7D :-(


Back to the Sandisk Pro, the strangest thing is that, it's a 16Gb card, files were in Jpeg (high) and there were counted 1350 on the card (number retrieved by the rescue software) , without the 7D counter getting below 500 remaining pics during the shooting.


What's more, the software used for rescuing files was showing (just like in a defrag software map) that half of the card was empty... ?!?


Finally, does this may have to do with low temperatures (we were at 3200 meters) ??


A final word : the 7D is a marvellous camera for sports (tracking is superb), and I was impressed also by the Sigma 120-400 which AF was flawless.


Thanks
