Focus Breathing Compensation

In most lenses when the focus is operated, the angular field of view changes much like zooming. This is called the zooming effect of focus or "breathing."

Utilizing digital control technology, Fujinon has solved this problem by enabling the angular field of view to remain constant by synchronizing the zoom movement to the focus movement, thus reducing image size change when focusing.

This feature is standard on 22x7BES, Ah20x8, Ah24x7, HA22x7.2 and HA26x6.7.
