The main part – the ability to capture 1920×1080 RAW video on Canon EOS 5D Mark III. Yes, it certainly capable to do so. However, it is only for 1920×1080 24p mode only. Not 30p mode as that require more than 103.6MB/s writing speed (and limited by 5d3 itself as its CF controller can write up to 100MB/s only). The test was run with Global Draw OFF. But rest assures that it can also record 1920×1080 24p with Global Draw On. By the way, you can record around 25 minutes 1920×1080 24p RAW video with this 128GB card. Take 64GB version if you don’t require to take long footage. As for normal photo shooting, it able to take burst mode up to 24 RAWs continuously.
