Hi, I just got my Canon 7D yesterday. I need a recommendation on a compactflash card. I was thinking of the Sandisk Ultra vs. Sandisk Extreme (keeping price in mind). What do the Canon 7D users here use? Please help. ............. Another note...I upgraded from a Canon XT so I've always used an off brand (from MicroCenter) cf card. I never really thought about the type of compactflash card I was using until I bought my 7D. Is this what is affecting my shutter speed on my camera? I can't seem to get the shutter speed to set at a higher fps.
