I am a total n00b when it comes to photography. My experience is limited to a digital point and shoot. I am finally ready to step up to a real camera and have ordered the Sony a65. My question is for someone who will be doing a lot of outdoor shooting what is the most reliable SD Card? I plan on only shooting stills and won't be doing any video recording. I am not worried about cost, I just want something that will have plenty of capacity. Also, is the class of the SD card important? Sorry for sounding like a total n00b, but I am one.
