Zhong Yi Optics Announces Mitakon 135mm f/2.5 APO Portrait Lens

Zhong Yi Optics, the leading wide-aperture lenses manufacturer in China, has rebuilt their old 135mm f/2.8 lens into 135mm f/2.5, available in Sony FE, Canon EF, Canon RF, Nikon Fx, and Nikon Z mounts. The new 135mm lens is ideal for working in difficult lighting with great control on depth of field. The lens is composed by high quality ultra-low dispersion elements that forms ultra-sharp images with minimal chromatic aberration. Well-built with metallic housing, the focus throw is comparatively long to give accurate focus control.

Buttery Smooth Bokeh

Mitakon Creator 135mm f/2.5 renders an exquisite bokeh by 9 blades of circular aperture. The background is softly blended like butter. Great control of depth of field can be achieved with focus technique, offering high level of creative potential with the lens. The perfect separation of subject from the background makes the lens ideal for portrait photography.

Premium Image Quality – Ultra Sharp, No Vignetting

Zhong Yi has improved the optical design of Mitakon Creator 135mm f/2.5 lens based on experience of producing 135mm lenses. 2 Super ED (extra-low dispersion) glass and 2 ultra-high refraction Index glass elements are precisely deployed to provide optimal sharpness. Images taken by it are showing sharp details even across the corners, with minimal field curvature to ensure the highest possible resolution is retained along edges of the area in frame.

Apochromatic (APO) Lens


Super ED and ultra-high refraction Index glasses incorporated design of Creator 135 f/2.5 lens help achieved the APO quality. Chromatic aberration is well suppressed to the slightest. No more distracting colour fringing is found along areas with highlighting parts over the image. A perfectly coloured, extraordinarily sharp portrait image with beautiful bokeh is achievable under strong lighting with this lens.

Premium Built Quality with Retractable Hood

Clear scale marking on aperture ring and focus ring are embedded on the robust metal barrel. Long focus throw enables precise focusing on target objects. Lens hood is designed to be longer than it used to, helping to reduce lens flare and ghosting.

Internal Focusing and No Focus Breathing

The new 135mm has an internal focus design, on which no extension/retraction on the lens housing when adjusting the focus ring. Filters, matt boxes, or other camera accessories can be mounted on it solidly. Focus breathing is designed to be minimal that the transition of shifting area in focus will be silky smooth.
