Description

AF Version:
Canon unique technology “Auto Focus System”

The need for an "Auto Focus System" in studio production

In HDTV systems that use the 2/3-inch format where typical studio settings might be, for instance, an aperture setting of f/2.8 and a focal length of 35 mm with a distance of 4.5 m from the front lens to the subject, the front depth of field is a mere 420 mm or less. The same settings in an SDTV system give a front depth of field of roughly 800 mm, demonstrating that the depth of field in an HDTV system is around half that in a similar SDTV system.

As a result, camera operators must continually work harder than in the past to maintain the focus, depending on the sensitivity of the focusing adjustments. This imposes a fatigue factor over time as they must also be attentive to image framing and camera moves that are actually the more creative aspect of their job.

Canon's unique Auto Focus Technology you can trust

What professional broadcast crews require in an AF system is “reliability”. Such AF systems must be capable of accurately capturing the images intended by the content producers.

The XJ27x6.5B AF uses Canon's own " TTL-Secondary Image Registration Phase-detection System", which is a version of the reliable AF system used in Canon’s single lens series reflex still cameras that has been customized for motion imaging with broadcast lenses. It is basically the same as the AF system first incorporated into Canon's long zoom field lens XJ100x9.3B AF in 2007, but uses optimized algorithms and control software to further enhance the precision available in studio production environments.

Features of Canon’s “Auto Focus System”
! Extremely high focusing accuracy in full HDTV specifications
! Ability to focus from a completely de-focused status without hunting
! Ability to focus on a high speed moving object
! Focusing speed can be varied to suit the scene
! Size and position of the AF frame (target area) in the camera VF can be changed from the Focus Demand FDJ-P31/P41.
