To take advantage of the X-series cameras’ mirrorless design, the rear element of the lens is as close as possible
to the sensor, minimizing the back focus distance appreciably. The lens construction includes a metal barrel,
Super EBC coating for improved optical performance, and it delivers improved center-to-edge resolution and
brightness free from chromatic aberration. The final lens element, positioned as close to the sensor as possible,
makes the incidence angle of the light reaching the sensor smaller, and thus reduces vignetting and color
shading, while helping to keep the lens’s overall size small. This lens has a maximum magnification of 0.14x,
and the aperture ring has 1/3-stop click stops for more precise exposures.
