The Polaroid SX-70 Onyx, released in 1981, is a special-edition version of the SX-70 folding SLR distinguished by its smoked translucent polycarbonate body, which allows the internal mechanism to be partially seen through the shell. It is mechanically and optically identical to the late-production SX-70 Model 2: the same 116mm four-element glass lens, the same silicon-blue-cell metered electronic shutter, the same folding SLR viewfinder with split-prism focus aid, and the same integral SX-70 film format. The transparent body is purely a design choice, one that reflects the late-SX-70 era's willingness to experiment with cosmetic variants after the camera's core engineering was mature. The Onyx is among the rarest and most visually distinctive of all SX-70 variants and commands a significant premium on the used market relative to standard production models.

The SX-70 was introduced in 1972 as Polaroid's most ambitious consumer product to that point: a folding single-lens-reflex camera using a then-novel integral film system in which the print self-developed without any peel-apart step. Edwin Land introduced it personally at a shareholders meeting and it became a sustained critical and commercial success. Over its production life, Polaroid released numerous SX-70 variants - the original chrome-and-tan leatherette, the black Model 2, the Sonar autofocus version, and a series of limited-edition bodies.
The Onyx appeared near the end of the SX-70's active commercial life, around 1981, when Polaroid was already developing the successor 600-speed integral film system. By that point the core SX-70 mechanism was well-proven and the main avenue for product differentiation was cosmetic. The smoked transparent shell of the Onyx was a radical departure from every prior SX-70 body: rather than leather, chrome, or painted surfaces, the body panels were molded in dark translucent polycarbonate that revealed the structural skeleton and some mechanical components beneath.
Production was limited - exact figures are not reliably documented - and the Onyx was sold at a premium price point reflecting its limited-edition positioning. It was discontinued as Polaroid transitioned its focus to the 600-series cameras in the early 1980s.
The Onyx is the most visually dramatic SX-70 variant ever produced and one of the most striking camera designs of the early 1980s. At a moment when consumer electronics were moving toward uniform black plastic boxes, Polaroid chose to make the mechanism itself the visual statement, anticipating the "see-through" industrial design trend that would emerge more broadly in technology products a decade later.
As a photographic tool the Onyx performs identically to any other late-model SX-70: it is an excellent manual-focus folding SLR producing the distinctive SX-70 print with its particular tonal palette and surface quality. The camera was used by a generation of photographers who found that SX-70 prints - with their soft, layered appearance and square format - offered something no conventional film could replicate. Andy Warhol was among the most publicly associated names with SX-70 photography in general, using the format extensively for his documentary and artistic work; the question of which SX-70 variants Warhol used specifically is not well documented.
The Onyx is now firmly a collector's object. Working specimens in good cosmetic condition are sought after both for use and display, and command prices well above standard SX-70 models.
