A bright telephoto prime featuring
an updated optical design, the Creator 135mm f/2.8 Mark II Lens from Mitakon Zhongyi is compatible with Pentax K mount full-frame and APS-C-format DSLRs.
One extra-low dispersion element is incorporated within the design, and helps to markedly reduce chromatic aberrations for increased clarity, sharpness, and color accuracy when photographing in strong lighting conditions. The f/2.8 maximum aperture also benefits working in difficult lighting and also affords greater control over depth of field for using selective focus techniques.
One extra-low dispersion element is incorporated within the
six elements, six groups design, and helps to reduce chromatic aberrations for sharper, clearer image quality.
