Exclude objects from being affected by DOF

Hello,

 

I have a scene with some objects in the foreground and a big plane in the background. I use the plane as a background object to make it appear in the refraction of one of the objects which is transparent. Now I want to enable DOF but it should just affect the objects in the foreground. The texture on the background object shows a room (we are talking about an indoor scene here) and it already has depth blur applied on it (through Photoshop). So I don't want the background texture to get blurred one more time. How can I exclude the background plane from the DOF?

 

Thanks, Daniel

z depth AOV? Wouldn't it look nicer if you rendered it all in camera (more expensive, I know)?

Yeah sure it would look better if I created the whole scene inside of C4D. But that's not worth the effort for this case.
I haven't thought about the Z depth AOV yet. But I think it would still not work because I have this glass object in the front and the area on the Z depth map with the glass would be brighter of course because the background plane is visible through. So the glass itself will get blurry and not just the object that is behind it (in my case the plane) if I use the Z depth map later.
