Depth of field and emitters

Hi

I’m playing with depth of field, it need tweaks, but is visible and working. Problem is with emitters:

This emitter is far away from dof as you can see, but is still razor sharp. This is “feature” or I missed some additional settings? This is screen from ‘New Editor Window’ not game.

Thank you.

Bump. I have bigger problems with UE now, but what about this?
