Description — Bronica 150mm F/4
The Bronica SQ 150mm f/4 Zenzanon PS is a prime lens built for the Bronica SQ medium format camera system. Operating at a fixed 150mm focal length, it falls into the telephoto range and is a natural fit for portrait distances and deliberate compositional work. The maximum aperture of f/4 provides a solid baseline for medium format shooting, and the lens accepts standard 67mm screw-in filters for easy accessory integration.
Weighing in at 600g, it strikes a practical balance between medium format build quality and everyday usability. Focus is entirely manual, placing creative and technical control squarely with the shooter. There is no image stabilization, so a measured shooting approach is recommended.
For photographers who are already working within the Bronica SQ system, this Zenzanon PS prime is a well-matched telephoto option that integrates seamlessly with the existing ecosystem.
