Medium format macro lens for Mamiya RZ67 cameras.

The Mamiya Sekor Z 140mm f/4.5 Macro is a medium telephoto macro lens for the Mamiya RZ67 Pro II medium format system. Z-mount (Mamiya RZ67's electronic bayonet) enables electronic coupling with the body. The integrated Seiko leaf shutter provides flash sync at all speeds — critical for macro studio work. On the 6×7 frame, this lens achieves close to 1:1 reproduction ratio.

140mm focal length, f/4.5 maximum aperture, built-in Seiko leaf shutter (flash sync at all speeds including maximum), Mamiya RZ67 Z-mount, approximately 1:1 reproduction ratio on 6×7 medium format, electronic coupling.

On the 6×7 format frame, near-1:1 reproduction captures subjects at life-size on the negative — more resolving power than 1:1 on 35mm due to the larger negative area. The leaf shutter enables full flash sync at any speed: essential for macro fill-flash and controlled studio lighting. Compared to the RZ67 110mm f/2.8 standard lens, the 140mm macro provides greater working distance at equivalent reproduction ratios — preferred for live subjects where proximity causes disturbance.

Test leaf shutter at all speeds, particularly 1/400s (verify the body/lens combination achieves the top speed). Test macro focus coupling and confirm reproduction ratio markings. Inspect aperture blades for oil contamination — a common failure mode on stored RZ67 glass. Check Z-mount electronic contacts for corrosion. Verify focus-extension coupling if extension tubes are used.
