The Mamiya RB67 Pro-SD (1990) is the third and final generation of the RB67 line. Same all-mechanical body, same rotating film back, same bellows focus, same Seiko leaf shutters in each lens. The "SD" indicates a **slightly larger lens throat** that accepts the new **K/L-series lenses** (multicoated, optically refined) — older Pro / Pro-S bodies cannot mount K/L lenses (they don't physically fit). The Pro-SD remains compatible with older Mamiya-Sekor C lenses backwards.

Released 1990 as the RB67 line's final iteration. Production ran 15 years until 2005, when Mamiya merged with Phase One and consolidated medium-format production around the 645 AF / RZ67 lines. The K/L lens series was developed specifically for the Pro-SD with refined optical formulas vs the older Mamiya-Sekor C lenses.
For 2026 buyers wanting the RB67 experience with access to the latest (and best) K/L lens variants, the Pro-SD is the choice. Used at $800–1,500 with one lens — slightly more than a Pro-S but with K/L compatibility. The K/L lens series — particularly the 90/3.5 K/L and 127/3.8 K/L — is genuinely sharper than the older C-series.
Trade-off vs Pro-S: same weight, same workflow, same image quality on C-series lenses; the K/L upgrade matters most for studio commercial work where lens performance differences are visible.
Mamiya RB K/L lens series: 50/4.5 K/L, 65/4.5 K/L, 90/3.5 K/L, 127/3.5 K/L, 180/4.5 K/L, 250/4.5 K/L, 350/5.6 K/L, 500/8 K/L. Older Mamiya-Sekor C lenses also mount on Pro-SD bodies. Same backs, finders, and accessories as Pro / Pro-S.
