Hi,

I use orthographic camera but cannot use focal blur with that type of
projection
Is there any solution to this problem ?

Get a functionning brain ?

Seriously, do you understand what is an orthographic camera/projection ?
Could you identify any focal or lenses for it ?
What would you expect from combining focal blur and orthographic ?
Why do you think so ?

It's not quite what you're asking for, but you can get something a little
bit similar using a standard perspective camera, but from a very long way
away.
You can 'zoom in' by adjusting the right and up vectors and set a very wide
aperture to bring your focul blur back.

camera {location<0,0,-250> look_at<0,0,0>
  right 4/3*x/20  up y/20
  aperture 10 blur_samples 10 focal_point<0,0,0>
}

Yikes .... was that necessary? Even tho the posters faux pas maybe obvious 
to some of us, it wasn't even close to warrenting your personal attack.

Jeez LF, that was a bit harsh.

And why, for that matter, shouldn't orth camera support focal blur? It
wouldn't correspond to any real-life situation, but then an ortho camera
doesn't really correspond to any real-life situation anyway. I've no idea
whether the source would support it, but why not allow for a focal blur
based on distance from a plane rather than distance from a point?
