Okay, from your last response to my question about maximising DOF and DR I either haven't understood correctly or...

what you mean is that for the FF camera you can get the same DOF and potentially an additional stop of DR by using a slower shutter speed (assuming that's a viable option) .

Your comment earlier where you said "for Equivalent photos, the FF sensor would collect the same amount of light, but the read noise would still be twice as much, so the ratio of the saturation limit to the noise floor would be have as much, and thus one stop less DR"

So if an equivalent photo (presumably using 2 lower F-stops to achieve the same DOF and receiving the same light as an M43 sensor) results in 1 stop less DR at the same shutter speed for sensors of the same efficiency /pixel density  how can a FF frame camera then have more DR when you want to maximise DOF in a landscape photograph unless you lower the shutter speed by 2 stops to increase the total light to 2 stops more than the M43 sensor ?

I'll browse your equivalence  tomorrow for an answer as it's late here
