Apr 12, 2011 06:47 | #1 Can anyone refer me to info on the minimum size CF card I will need for HD video on the 7D? Say for a 60 minutes program at maximum video settings...will my Lexar Professional 300x 8GB CF be enough? and at what point does the "speed" on these CF cards pay off or is wasted? 30MB/s good enough or do I really need the latest 60MB/s or 90MB/s? Body: 5D MKIII Gripped, 7D MKII
