Canon rates the 1D X Mark II buffer depth at up to 170 RAW images, with the highest number requiring a CFast 2.0 Memory Card. CFast cards were a new requirement for my kit and Transcend was anxious for me to try out one of their CFX650 256GB CFast 2.0 Memory Cards (Max. Read/Write Speed: 510/370 MB/s) in this camera. I didn’t have to think too long to accept that offer and, while I have yet to use another card in this camera, I can tell you that this one and the 1D X Mark II perform very impressively together.
With the Transcend card installed, the 1D X Mark II captured an incredible 14 frames per second until I got bored holding the shutter release down over 6 minutes later. The 14 fps converts to 840 fpm and, in 6:01.35, I had a VERY impressive 5,068 RAW images on the CFast card. With this card installed, the camera never filled its buffer. And, the sound is, as expected, awesome:

Here is a burst rate comparison between the 1D X Mark II and several other current or recent models:
Burst Comparison: 80D, 7D Mark II, 1D X Mark II and 1D X
The fine print: the test camera was configured to use ISO 100, a 1/8000 shutter speed (no waiting for the shutter operation), a wide open aperture (no time lost due to aperture blades closing) and manual focus (no focus lock delay). The lens cap remained on (insuring a black file and the smallest file size) and a freshly-formatted fast memory card was loaded. Camera sounds were recorded using a Tascam DR-07mkII Portable Digital Audio Recorder with record levels set to 50% at -12db gain and positioned 1″ behind the rear LCD.
Completing the full 1D X review is of course a high priority for me – I’ll have much more to share in the near future. Check out the Canon EOS 1D X Mark II page for more information.
