The Koni-Omega Rapid 100 (1968) is a 6×7cm medium-format press-style rangefinder camera built by Konishiroku Photo Industry (Konica) in Japan and sold in North America under the Koni-Omega brand through Berkey Photo. It is a direct successor to the original Koni-Omega Rapid (1964), retaining the same fundamental architecture — push-pull film advance, interchangeable film magazines, interchangeable leaf-shutter lenses, coupled rangefinder — while incorporating revised film back sealing and ergonomic refinements to the magazine latch system.

Konica introduced the Rapid 100 in 1968 as the first major revision of the Koni-Omega press camera concept. The "100" designation reflected both the revised model numbering scheme and a nod to the 100-series update philosophy then common in Japanese camera manufacturing. Key changes from the original Rapid were an improved film-back locking mechanism to reduce light leaks, a revised advance mechanism with firmer detents, and a cleaner lens-release system.
The Rapid 100 sold alongside the original Rapid for a period, then became the primary press camera offering until the introduction of the Koni-Omega 200 in the mid-1970s. The 200 brought electronic automatic exposure to the line — a significant shift in philosophy. The Rapid 100 remained in use in professional settings where fully manual operation was preferred.
The Rapid 100 represents the mature form of the push-pull Koni-Omega concept before the line moved toward automation. It is interchangeable with the original Rapid's lenses and backs, making it part of a unified system that photographers could build up over time. Today it offers a relatively affordable path to 6×7 medium format with a sharp Hexanon lens and full-speed flash sync — advantages that remain practically useful for film photographers.
Same lens family as the original Koni-Omega Rapid:
Film magazines are interchangeable for 120 and 220 film. Backs from the original Rapid are compatible, though sealing quality may vary between generations.
