Description — Bronica 100mm f/4.5
The Bronica 100mm f/4.5 Zenzanon RF is a medium format prime lens designed exclusively for the Bronica RF rangefinder camera system. Operating as a telephoto prime with a fixed 100mm focal length and a maximum aperture of f/4.5, it is a purposeful optical tool for medium format rangefinder photographers who need reach beyond a standard focal length. Focusing is entirely manual, placing full creative control in the photographer's hands — a natural fit for the rangefinder shooting discipline.
With no image stabilization, careful technique is essential. The lens is tailored to the Bronica RF mount, making it a system-specific choice for shooters already working within the Bronica RF ecosystem. For medium format film photographers seeking a telephoto prime that integrates natively with their rangefinder bodies, the Zenzanon RF 100mm f/4.5 is a dedicated and purposeful addition to the kit.
