Welcome to the club!
I suppose you are talking about focal blur and depth of field like in a
Real Life camera. Basically, the cameras in POV-Ray are pinpoint
cameras, i.e. they do not have a lens for focussing. As a result the
scene is always sharp from foreground to background.
However, focal blur (or depth of field) can be simulated in POV-Ray. The
best you can do presently imo, is to play with the example camera scenes
that are present in the scenes/camera folder of POV-Ray. You will find
there the focalblur.pov scene which you can use, besides all the other
camera types of course.
