Beautiful macro image thanks to newly adopted AF system
Adopts Floating Focus System*, divides focus lens group into Front Focus Group and Rear Focus Group, and drives them depending on the shooting distance with high accuracy. This system leads to high resolution when shooting macro, where the aberrations become easily noticeable.
A newly developed Ball Slide System controls lens movement by arranging ceramic balls along the guide rail. This system makes it possible to achieve high image quality from the center to the edge by suppressing any inclination of the two focus lens groups and keep its clearance with high accuracy.
The focus lens groups move within the lens barrel meaning that the length of the lens does not change. Therefore there is no need to worry about accidentally touching the object you are shooting.
OIS suppressing Shift Shake** - The lens has adopted the Optical Image Stabilization system to suppress shift shake, which can have a larger impact when shooting macro. Angle shake and shift shake is suppressed by using a gyro sensor and an acceleration sensor with high accuracy, which achieves 5-stop image stabilization (CIPA guidelines).
Fast and quiet AF - The focus lens is driven by a linear motor which is both quiet and quick, achieving fast and silent AF.
* Focus System suppresses aberration fluctuation by driving two focus groups with high accuracy.
** Image shaking is caused by vertical and horizontal movement and becomes more obvious the higher the magnification ratio.
