The Canon C70 4K video camera is a new generation of RF mount cinema EOS system camera with Canon's 4K Super 35mm DGO sensor. With 4K 120P Slow Motion, High Dynamic Range and Dual Pixel CMOS AF in a compact body, the RF system takes you into a brand new era. The Canon C70 comes with an RF mount, but can be adapted to all EF lenses using the 0.71x converter, even with a full field of view. The camera can record different codecs and resolutions on two separate storage media. The autofocus and face detection are great. IBIS stabilization (best with RF lenses) allows shooting in low light. Function depends on the lens used, Digital 5-Axis IS for non-IS lenses. Combination of optical IS and digital IS for combined 5-axis IS. IS performance depends on the lens used.
