The Zenza Bronica ETR-S Black is the black-body variant of the ETR-S, introduced in 1979 as the refined successor to the original ETR (1976). The ETR-S introduced improved electronics, a new metering interface, and compatibility with the expanding range of ETR-system accessories. It shoots 6x4.5 cm (645) frames on 120 or 220 film - 15 or 30 exposures per roll respectively. The leaf shutter is housed in each lens, not the body, giving the system one of its most significant practical advantages: full flash synchronization at all shutter speeds up to 1/500s. The black-finish variant was marketed alongside the standard silver/chrome body. Metering requires an accessory prism finder; the body alone provides no exposure information.

Bronica launched the ETR in 1976, marking the company's shift from focal-plane 6x6 designs (S, S2, S2A, EC) to leaf-shutter 645. The 645 format offered more frames per roll and a smaller body than 6x6. The ETR-S (1979) refined the original ETR with improved electronics, a dedicated AE prism interface, and minor mechanical improvements. It was followed by the ETR-Si (1989), which added TTL flash metering. The entire ETR line was eventually discontinued as Bronica was absorbed by Tamron, with production ending in the early 2000s. The black variant of the ETR-S was available throughout the S-generation production run but appears in smaller numbers on the used market than silver bodies.
The ETR-S arrived as medium-format photography was becoming more accessible to working photographers who could not justify Hasselblad prices. The 645 format's economy (more frames per roll) and the system's leaf-shutter flash sync made it attractive for wedding and portrait photographers. Full flash sync at all speeds - a capability that focal-plane cameras of the era could not match - was a genuine competitive differentiator. The black-finish variant was preferred in some studio contexts and by photographers who wanted a less conspicuous body on location. Zenzanon ETR lenses, while less celebrated than Zeiss or Nikon glass, earned a solid reputation for contrast and sharpness in the 75-150mm range.
The ETR mount system offers a wide range of Zenzanon PE lenses:
All lenses carry the leaf shutter and aperture-priority coupling. Key accessories:
