25.0MP Full frame (35.9 x 23.9 mm ) sized Partially-Stacked CMOS sensor and features Expeed 7 processor.
Below you can see the PYXIS 6K and ZR sensor size comparison.
Sensor Size and Resolution Comparison image of Blackmagic PYXIS 6K and Nikon ZR Cameras
Blackmagic PYXIS 6K and Nikon ZR have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Blackmagic PYXIS 6K
or the
Nikon ZR ,
including hyperfocal distance.
