The Polaroid 660 Transparent is an instant film camera with a clear-bodied variant of Polaroid's folding 600-series rangefinder design. It was produced as a promotional or display version of the standard 660, retaining the autofocus and built-in flash arrangement of the regular model.

Sales data for the 660 Transparent is thin, but a single UK auction hammer result in October 2025 saw an example sell for £504, indicating that as of 2026 the clear-body variant is worth substantially more than a standard 660. Because this is a wholesale saleroom price rather than a retail figure, dealer asking prices today can sit higher, and the value is highly condition- and completeness-sensitive given how rarely these come up.
