Odd image effects around edges of the camera

Hello, I am getting an odd effect on a house model, but only for this model. The images attached show the outline of the main camera in the scene and there is a blur that I can not seem to get rid of. This effect is more pronounces as the camera rotates towards the edge of the building (the effect stretches). I have changed materials and tried some of the other settings but no luck.

Has anyone seen this before? Can you help point me in the right direction?
