High resolving power and beautiful bokeh
An optical construction of 16 elements in 12 groups, including one aspherical lens, one Super ED lens, and three ED lenses has been adopted. Chromatic aberrations are suppressed by arranging the ED lenses in a well-balanced position and spherical aberrations are suppressed thanks to the aspherical lens, securing high resolution performance.
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.
Weather and Dust resistant, -10°C low-temperature operation with fluorine coating
The lens features 11 weather and dust resistant seals, allowing you to shoot with confidence in tough outdoor environments.
The fluorine coating, which has been applied to front lens elements, is water repellent, less susceptible to smudges and is easily cleaned.
