Superb light transmission due to Fujifilm’s unique SUPER EBC FUJINON multi-coating on all light-transmitting surfaces including the lens elements and prisms. The ED lens elements effectively control the chromatic aberration and prism coating for a superior image resolution as well as contrast. This also allows for a much brighter field of view. The optimal placement of nine lens elements in seven groups controls distortion across the entire view from the center to the edges.
