Sensor Size and Resolution Comparison image of Sony FX5 and Canon 1D X III Cameras
Sony FX5 and Canon 1D X III 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
Sony FX5
or the
Canon 1D X III ,
including hyperfocal distance.
