A combination of high-speed, nimble focusing performance and robust image stabilization makes this mid-telephoto ideal for photographing and tracking fast moving subjects.
- A high-thrust HLA (High-response Linear Actuator) quickly moves the lightweight focusing group for quick focus switching and nimble tracking of fast-moving subjects.
- Three separate AFL buttons make it easy to control focus position while tracking subjects.
- Focus Mode and Focus Limiter switches give further control on focus speed and range for even more control depending on what the subject is and how far away it is.
Helping to achieve sharp and stable images, this 200mm features a robust image stabilization system that compensates for 6.5 stops of camera shake. Powered by Sigma's OS2 algorithm and using a dedicated drive unit, actuator, and high-precision sensor, this stabilization system is perfectly matched to the larger size and wider aperture design of this lens.
Additionally, for more refined control, two OS modes are available:
- Mode 1 is a general application stabilization mode, suitable for most photo and video situations.
- Mode 2 is a specialized setting for panning work and makes use of the OS2 algorithm to better stabilize shots while moving the lens horizontally, vertically, or diagonally, regardless of the camera's orientation.
