All Panchro/i Classic prime lenses are colour balanced, colormatched and compatible with Cooke 5/i, S4/i, miniS4/i and Anamorphic/i. Every index mark is labelled. More detailed markings allow for more detailed focus control.
Our Academy Award® winning cam-style focus movement coupled with the added benefit of a large lens barrel diameter, has allowed for an increased number of focus markings, particularly at close focus. Spherical aberration has been controlled throughout the range of focal lengths to eliminate compensation of changes in back focus with aperture. A four-point contact bearing provides a smooth positive backlash-free movement.
