Dedicated Macro Lens. With 35mm focal length equivalent to 94mm after the sensor crop-factor, the 120mm f/4 Macro offers users true 1:1 macro capability. It has a 15.4-inch minimum focusing distance, with a focus-limit switch for setting the focusing distance range to increase autofocus speed. Additionally, it enables the lens to be very useful as a portrait lens.

Optics. The 120mm f/4 Macro features an extra-low dispersion element that minimizes chromatic aberrations and provides sharp, high-contrast images. It uses a floating mechanism and an independently moving aperture mechanism to maximize out-of-focus areas.

Please Note. This is a legacy lens that was originally designed for medium-format film cameras. We’ve noticed that it tends to slightly front- or back-focus, so you’ll want to make sure you microfocus adjust before you start shooting.
