Reader Asks: Depth of Field
Reader Jim S writes:
I'm finding these articles very instructive. Many thanks Lloyd.
But please would you amplify the comment " (e.g. hardly any depth of field, in terms of sensor potential)."
I am not sure that I understand precisely what you are saying here?
DIGLLOYD: Depth of field (DOF) is an amorphous concept. What I meant is that full sharpness on a 36-megapixel sensor is strictly limited to a a very shallow zone (which is not necessarily a geometric plane). Moving beyond that shallow zone, there is increasingly lower resolution than what is in theory possible with a 36MP sensor.
Please see What Does Depth of Field Mean on a 36 Megapixel Camera?.
