Is there an issue with this setup i am not considering?

The Polaroid SX-70 Sonar, a folding medium format instant print SLR, and an engineering marvel of its day, used ultrasonic sound for focusing. The focus would be wrong when photographing through windows or screens, and so the camera also had manual focus. I it would also have problems when focusing through foreground matter, such as foliage, flowers, etc., as sometimes used in portraiture.

Modern optical focus is far more precise in selecting the required subject of focus. The Polaroid solution wasn't all that great, a gimmick in my opinion.
