The DIGISUPER 27 AF features outstanding HD optical performance that will dramatically improve HDTV studio imagery. The key optical performance features include minimized distortion, even though the wide angle has been expanded to an exceptional 6.5mm. This lens also offers significantly reduced Ghosting and Flare. Reaching this incredible optical quality is only possible because of Canon's unique optical design concept, the POWER OPTICAL SYSTEM.

Canon design innovation that uses a floating optical system to better control chromatic aberrations
switchable operation between 16:9 and 4:3 aspect ratio imagery Wide Attachment (Optional
switchable system controlled from the associated camera that can switch in the optical extender system or the aspect ratio converter (an additional position allows for future new possibilities)
HD video's tremendous picture detail demands precise focus. Canon's extensive experience in long zoom field-lens design provides a unique understanding of the challenges camera operators face in simultaneously paying close attention to picture framing and control of the lens and camera, while also continually maintaining sharp focus on selected objects within complex scenes. Canon's new DIGISUPER 27 AF uses a sophisticated auto-focus technology based on an HD implementation of the Through-the-Lens Secondary Image Registration Phase Detection method
