Is that true?
In reply to Horshack, Feb 21, 2013

Are hardware-measured far and close edges of the in-focus range range the same as the far and close edges of the range of perceived acceptable sharpness ?

"When the circle of confusion becomes perceptible to our eyes, this region is said to be outside the depth of field and thus no longer "acceptably sharp."  Are we now saying that AF sensors are affected by the same effects as our eyes ?
