The SIGMA Art series is designed for very high sharpness and contrast already at full aperture with low chromatic aberration. The 9-blade rounded iris contributes to soft, smooth bokeh.
Canon EF mount with HSM autofocus and permanent manual fine-tuning. These are photographic lenses without cine gear and stepless iris, so a gear ring is needed for follow focus.
