I am rendering a walk-through to a serialized still image sequence. I am very confused about focus. The walk-through begins outdoors and proceeds indoors. The outdoor frames are noise free and well exposed and razor sharp. The indoor frames are noisier, but well exposed and focused. My confusion regards the transitional frame where the camera is outdoors, but framing an interior scene. This is wildly out-of-focus though well exposed. Why? What is Octane doing to determine focal length and how is this situation confusing it?

I have found a second frame that is problematic. Comparing the two out-of-focus frames suggests to me that Octane autofocus focuses on the foreground, not the center of the frame. However, the first frame had nothing in focus, so I am not sure about this.
Can one's focal depth setting be set wrong such that it forces a whole scene out of focus?
