The Zhong Yi Optics APO 135mm F2.5 ED is a mid-telephoto lens ideal for portrait photography. Its APO (apochromatic) design, combining two ED (extra-low dispersion) lenses and two ultra-high refractive index lenses, ensures precise imaging performance all the way to the edges of the image while minimizing chromatic aberration and color fringing. Its nine-blade circular diaphragm also produces exquisite bokeh, softly blending into the background.
