The Bronica GS-1 W (~1988) is a variant of the GS-1 system, typically sold as a kit pairing the standard GS-1 body with the Zenzanon-PG 65mm f/4.5 wide-angle lens. The underlying body is mechanically identical to the GS-1: a modular 6x7 cm medium-format SLR using electronic Seiko leaf shutters in each Zenzanon-PG lens, interchangeable film backs (120/220/Polaroid), and optional viewfinders including the AE-G metered prism. The "W" designation marks the wide-angle kit configuration rather than a distinct model line.

Bronica introduced the GS-1 in 1983 as its sole 6x7 SLR. As the system matured, Bronica offered kit configurations to target specific shooting contexts. The "W" kit packaged the 65mm PG wide-angle lens as the standard optic, positioning the system for architectural, landscape, and editorial photographers who needed a wider field of view than the 100mm kit lens. Production continued alongside the standard GS-1 until Tamron wound down the Bronica brand in 2002-2004.
The GS-1 line never matched Mamiya RB67/RZ67 sales volume, but it maintained a dedicated following among photographers who valued the leaf-shutter's flash-sync advantage and the lighter ~1.9 kg loaded weight compared to the RB67's ~2.7 kg.
The 65mm PG lens (equivalent to approximately 33mm in 35mm terms) gives the GS-1 W a wide rectilinear perspective suited to interiors, architecture, and environmental portraiture. Combined with full leaf-shutter flash sync at all speeds, the wide-kit configuration is particularly useful for mixed ambient/flash work where a focal-plane camera would require dragging the shutter or accepting hard-sync cut-off.
For contemporary film photographers, the GS-1 W represents a cost-effective way to enter the 6x7 format with a purpose-matched wide lens. Comparable Mamiya RZ67 + 65mm ULD kits typically command higher prices, and the Pentax 67 + 45mm combination cannot sync flash above 1/30s.
Full Zenzanon-PG system is compatible: 50/4.5 PG, 65/4.5 PG (this kit's primary lens), 100/3.5 PG, 110/4 PG Macro, 150/4 PG, 200/4.5 PG, 250/5.6 PG. All film backs interchange between GS-1 and GS-1 W bodies: 120, 220, 4.5x6 (645 mask), Polaroid. Finders: folding waist-level (standard), AE-G prism (required for aperture-priority and TTL flash), magnifying chimney finder. Accessories: Speed Grip-G, Motor Drive Wind Grip.
