Zenza Bronica GS-1 6x7 Camera with 100mm F/3.5 Lens (USED)

The Zenza Bronica GS-1 is a legendary 6x7 medium format SLR camera, highly regarded for its modular design, versatility, and professional-grade image quality. Introduced in the early 1980s, the GS-1 was designed to compete with other popular 6x7 cameras, such as the Mamiya RB67/RZ67 and Pentax 67, offering photographers a lighter and more compact alternative without sacrificing image quality.

Key Features of the Zenza Bronica GS-1

1. 6x7 Medium Format Excellence

The GS-1 produces huge 6x7 negatives, offering exceptional detail, tonality, and depth of field control. This format is ideal for professional applications such as portrait, fashion, landscape, and commercial photography.

2. Modular System

Much like other Bronica cameras, the GS-1 features a fully modular design, allowing photographers to customize their setup. The camera supports:
Interchangeable lenses (from wide-angle to telephoto)
Interchangeable film backs (120, 220, Polaroid, and even 135 panoramic backs)
Interchangeable viewfinders (waist-level, prism, and metered prisms)
Various grip options for improved handling

3. Leaf Shutter Lenses

One of the standout features of the GS-1 is its leaf shutter lenses, which allow flash synchronization at all shutter speeds (up to 1/500s). This makes the GS-1 an excellent choice for studio and outdoor flash photography.

4. Compact and Lightweight for a 6x7 SLR

Weighing around 1.6kg (without accessories), the GS-1 is significantly lighter and more compact than its Mamiya RB67/RZ67 competitors. Its ergonomic design and optional speed grip make handheld shooting more practical compared to bulkier 6x7 cameras.

5. Reliable Mechanical and Electronic Operation

The GS-1 is a hybrid system, using electronic controls for shutter operation while maintaining a robust, mechanically solid build. It requires a 6V PX28 battery, but the camera can still function in some capacities if the battery dies.
