Hi,

I'm wondering if I could change scale of focused area. I can define center of focus but how can I influence width. I presume it will change in according to focal length but unfortunately I can't change it so I'm looking for other option(like aperture is).

Is there way or I have no luck ?

Hmm, you are right. This parameter is missing.
(Same as in the XSI DOF shader, automatic mode). I will add it for the next version to give you more control.

At the moment the blur strength you set is reached at the camera.
So if you move the camera to the target, then the area in focus gets smaller.

You could use an expression to rescale the strength based on the camera<>focus distance

Great! I'm looking forward. It's very important parameter for me.

Thank you.
