Spherical Camera Clipping in Cycles Workaround ???

Hello,

I’m doing some interior visualisations currently and I would like to place my camera outside of the rendered room to get better looking perspective. The problem is that I cannot use the Camera Clipping option in Cycles to hide the wall from the camera, becouse it doesn’t work as clipping plane but as clipping sphere (so I get black circular edges). Is there a nice workaround for this problem? I know that I can uncheck the camera visibility of all the unwanted objects but it’s quite tedious process if you have multiple cameras and many objects in the scene. You cannot also hide only a part of an object and splitting instanced linked objects is also not a solution.

Is there a way to set clipping PLANE in Cycles (easily)?
