Sorry to start a thread that probably exists somewhere else, but I am reaching out for experience with certain SD cards instead of just in general... or at least that is what I will say as a cover I have always used SanDisk Extreme SD cards (32GB) since they came out. I just bought a Sony last night on the Amazon deal. If memory serves (I am not in a place where I can look for sure), the Extreme is rated at a 45MB/sec and the Sony is rated at like 94MB/sec transfer rates. I think the write speeds AR probably pretty close to eachother so I don't expect any major performance boost while shooting stills or video, but was wondering if anyone could share some experience with the Sony? I currently am shoot a NEX 6 RAW+JPG and doing some casual video in ACVHD @ 60p (yeah, I know that is probably not the best format for casual video of my kiddo, but I am abitious!) I have an a6000 on order and plan on shooting the same with it.
