| Polaroid Sun 660 Autofocus|
The Polaroid Autofocus 660 was a square-bodied instant camera in Polaroid's 600-series. It was the first in the range to use Polaroid's patented Sonar Autofocus device. The distance to the subject was calculated by emitting an sonar (ultrasonic) pulse which then was captured again. The time difference between the sent versus received pulse gave the distance measurement. The sonar emmiter/receiver is the big gold disk next to the lens.
- Lens: 116mm, f/11, Single-element plastic.
- Sonar autofocus (sharpest at 4-5 feet).
- Shutter: electronic; automatic speed between 1/4-1/200 sec.
- Integral auto flash that works in low light can be forced on or off.
- Polaroid's Light Management System (the darken/lighten exposure correction slider).
