By adopting an optical design of 19 elements in 14 groups, including 2 FLD and 2 SLD glass elements, axial chromatic aberration and magnification
chromatic aberration, which are easily noticeable in telephoto lenses, are thoroughly corrected, achieving exceptionally high optical performance.
Even at wide-open aperture, it delivers finely detailed rendering that maintains high resolution and contrast from the center to the edges of the frame.
With the large bokeh enabled by the F2 aperture, which boasts twice the light amount of F2.8, and the compression effect of the 200mm focal length,
the lens delivers a gorgeous background blur that brings out the subject, achieving a unique expression. Combined with its exceptional optical
performance, it makes it possible to take impressive portraits like no other.
The F2 brightness allows for a faster shutter speed even in low-light environments, making it a powerful tool for indoor sports photography. The
large bokeh enhances the movements and expressions of the athletes, creating dynamic images, and with the high-speed AF made possible by the
HLA (High-response Linear Actuator) motor and Optical Stabilization (OS), that decisive moment is not missed, even in fast-moving sports scenes.
Using advanced simulation technology, flare and ghosting have been largely eliminated, ensuring that the lens renders rich, high-contrast results in all
conditions. In addition, Sigma’s Nano Porous Coating and Super Multi-Layer Coating have been applied to further suppress flare and ghosting.
The HLA (High-response Linear Actuator) motor is incorporated, achieving high-speed AF. It combines accelerated focusing speed with outstanding accuracy.
The OS2 optical stabilization algorithm provides an outstanding image stabilization effect of 6.5 stops. The lens is equipped with two OS modes: Mode 1 is suitable for general shooting, and Mode 2 is ideal for panning shots of motorsports and other sports. In Mode 2, Sigma’s Intelligent OS, an algorithm specially designed for panning shots, enables effective image stabilization even when the camera is moved vertically or diagonally, regardless of the horizontal and vertical orientation. This ensures that the subject’s movement can be captured without losing the panning shot effect.
The exterior of the lens body is coated with a thermal insulation paint that effectively suppresses heat absorption from sunlight. This prevents the lens
from heating up, even during long outdoor shoots in sunny weather.
The mount joints, manual focus ring, zoom ring, custom switches, and exterior joints are all protected from dust and splash by a dust- and splash-resistant structure. Further, the frontmost surface of the lens is coated with a water- and oil-repellent coating to facilitate maintenance when water droplets or dust adhere to the lens.
A new tripod socket, TS-171, has been designed with its use as a carrying handle in mind, featuring a longer base and wider spacing between it and
the lens. The tripod ring incorporates a 90° click mechanism, allowing for smooth and secure rotation, and the foot is compatible with Arca-Swiss type
clamps.
There are various functions to support shooting, including AFL buttons in three different locations, a focus mode switch, a focus limiter switch, an OS
switch (Mode 1/2), and a custom mode switch.
