Manufacturer description #1

The 120mm f/4 macro is the first of its kind for medium format optics, featuring continuous focusing from infinity to 1:1 life size. Its unique double helicoid and floating element design assure optimum performance at all working distances. Applications include any subject from landscapes and wildlife to full length portraits, to head and shoulders shots to close-up beauty, product shots or macro, scientific and industrial applications.

Manufacturer description #2

This MACRO A 120mm F4 M lens has a built-in floating system (a device to move a part of lens system so as to correspond to the shooting distance), which automatically corrects for close focus aberrations to effectively increase edge sharpness at close focusing distances. This increases overall performance for close-up and general photography at all distances.

Because of its unique built in extension helicoid barrel, the lens can be focused from infinity to life size reproduction (1:1) without any accessories.

The lens barrel design shields the front lens element sufficiently without requiring an additional lens hood. However, if desired, the Mamiya screw-in hood M67-No.4 may be used.
