Bob,

My program says
That for a given depth of field for example 3meter to infinity
For 36*24= about F 17.0 standard lens aprox 50 MM
For 18*12 = about F 8.5 standard lens aprox 25 MM

Sensor area=1/4
For a given shutter speed

Same mega pixels same resolution

You now need a higher ISO for the full frame
How translate this in noise
Is having a full frame for a given depth of field any better for noise?
In this example?

PS the lens 8 times lighter 2*2*2 –glass
Berl.
