Depth of field

Hi all

maybe a silly question, but when the Physical Camera’s depth of field is switched on, what is the default Focus Distance, or is the centre of the image in focus? This is using a camera only (without aim etc.)

Cheers

Its the Center Of Interest parameter of Mayas’ Cam (this parameter always exists no matter if the Cam is without or without Aim):

Cheers for the info.

Is the numerical value setting an area of the center, and not distance? If so, is the center always in focus?
