The Koni-Omega Rapid 100 is a robust, 6x7 medium format rangefinder press camera known for its sharp lenses, quick film advance lever (like a rifle bolt), interchangeable film magazines (120/220), and built-in parallax-correcting viewfinder, popular for professional work like weddings due to its leaf shutter (flash sync at all speeds), sturdy build, and ability to produce large, detailed negatives. It features a unique left-handed grip, three cold shoe mounts, and requires manual exposure settings, offering a compact yet capable alternative to medium format SLRS.
