As a lens is mounted, the camera automatically detects compatibility with the firmware. Once compatibility is confirmed, the user can then select special-edition Custom Images.

HARUBENI (spring rouge) is the fourth special-edition Custom Image mode.

When partnered with a lens that renders a soft, delicate image description, it sets the contrast a high level to deliver an image highlighted with pink and red shades — the symbolic colors of Japan’s spring.
