Lens Overview — Nippon Kogaku 7.5cm f/2.8

The Bronica 7.5cm (75mm) f/2.8 Nikkor-P is a vintage medium format lens manufactured by Nippon Kogaku during the 1960s. Designed specifically for the Bronica SQ lens mount, it is built to serve photographers working with 120 film format medium format cameras. As a manual focus lens, it places full control of focus in the photographer's hands — a characteristic that many film photographers and collectors actively seek out in vintage glass.

One of its more distinctive technical features is the integrated leaf shutter, which allows flash synchronization at all shutter speeds, a notable advantage over focal-plane shutter systems. The lens carries a maximum aperture of f/2.8, offering a reasonably bright viewing and shooting experience for a medium format optic of its era. Manufactured in the 1960s, it represents a period of careful optical craftsmanship from Nippon Kogaku, a name closely associated with precision Japanese optics.

This lens is well suited to collectors of vintage medium format equipment as well as working film photographers who shoot 120 format and want a period-correct, manual-focus solution on a Bronica SQ-compatible body.

Key Features — Nippon Kogaku 7.5cm f/2.8

75mm f/2.8 Aperture: A maximum aperture of f/2.8 provides a relatively bright image for a medium format optic, useful for lower-light shooting and subject separation.

Nippon Kogaku Optics: Manufactured by Nippon Kogaku in the 1960s, the forerunner to Nikon, representing a period of precision Japanese optical craftsmanship.

Integrated Leaf Shutter: The built-in leaf shutter allows flash synchronization at all shutter speeds, unlike focal-plane shutter systems which are limited to a specific sync speed.

Early Bronica S Mount: Designed for the original Bronica S system bodies, not the later Bronica SQ system — verify mount compatibility before purchase.

Medium Format Coverage: Covers the 120 film format, delivering the larger negative area and characteristic rendering that medium format is known for.

Manual Focus Design: Full manual focus operation gives the photographer direct, tactile control over focusing — a workflow favored by many film photographers.

Description — Nippon Kogaku 7.5cm f/2.8

The Bronica 7.5cm (75mm) f/2.8 Nikkor-P is a vintage manual focus medium format lens produced by Nippon Kogaku during the 1960–1969 era. It is designed for the Bronica SQ lens mount and built around 120 film format medium format cameras. A defining mechanical feature of this lens is its leaf shutter, which sits within the lens body and enables flash synchronization across the shutter's full speed range — a practical advantage that distinguishes it from focal-plane shutter designs.

With a maximum aperture of f/2.8, the lens offers a solid balance of light gathering and compact form for a medium format optic. As a fully manual focus design, it appeals to photographers who value deliberate, hands-on shooting technique. Whether you are building a working Bronica SQ film system or adding a piece of 1960s Nippon Kogaku optical history to your collection, this lens represents a well-defined, mount-specific option for the medium format film community.
