The Canon 1D-X Mark III is the new professional standard for full-time big-league pro sports shooting – and every kind of shooting. It is a big beast but, as it happens, it’s exactly the same size dimensionally as its predecessor, albeit 90g lighter. For starters, it can shoot 5.5K RAW video internally at 50fps using the full width of the sensor and with 10-bit color. The 25/30 and 24fps options are also available. The 4K DCI resolution is derived from the 5.5K readout and downsampled so it again uses the full width of the sensor to give a 17:9 aspect. Again, it’s recordable internally at 50/60fps and with 10-bit 4:2:2 color when shooting in Canon Log with H.265 HEVC compression.
