The KJ22ex7.6B IRSE is one of Canon's HDgc Series production lenses, designed for portability and affordability, offering a generous range of focal lengths as well as a wide range of view. As the successor to the KJ21ex7.6B, improvements include reduced focus breathing, Large Diameter Aspherical lens elements that provide better control of comatic aberration, geometric distortion, and corner resolution, and reduction of the curvature of field and chromatic aberrations. In addition to better optical performance, the KJ22ex7.6B also features a new design of the digital drive unit that improves user interface with the control of zoom, iris, and focus.
