Please mouse over each part of the nomenclature to see it explained.
Auto-Adjustment of Back Focus: A switch located on
the front side of the lens’ drive unit, allows the user the
ability to adjust the back focus automatically and accurately.
High Speed Focus, Low Noise: By adopting a Rear
Focus System design, the lens features high speed focusing of 1.5sec
(when controlled by remote manual operation) while at the same time,
decreasing the motor noise of the lens.
Optical Performance: Regardless of the distance
of the object being, it will always maintain high optical performance.
Rear Focus System: Since focusing is adjusted
behind the zoom lens unit instead of in front of the lens this allows
the focus lens unit to be become much smaller and lighter resulting
in a high performance focus response.
