You are right, it probably is the zoom/focus. 12 on the y axis is probably way too close to the ground with those defaults. If you change the Y axis to 100 or 200 does the floor still get clipped? If it doesn't, then try setting it back to 12 (if you need it to be 12), and then changing the zoom/focus to fit. Hopefully it works for you.
