Core Technical Specifications
- Focal Range: 200–600mm (3.0 X zoom). On APS-C cameras, this provides a 300–900mm equivalent reach.
- Aperture: Variable f/5.6 to f/6.3. It maintains f/5.6 until approximately 300mm, then shifts to f/6.3.
- Internal Zoom Design: Unlike many competitors that "telescope" outward, this lens does not change physical length when zooming. This improves weather sealing and keeps the center of gravity stable, which is a significant advantage when using a gimbal or tripod.
- Autofocus: Driven by a Direct Drive Super Sonic Wave Motor (DDSSM), providing fast, near-silent, and highly accurate tracking for fast-moving subjects.
- Optical Stabilization: Built-in Optical SteadyShot (OSS) with three dedicated modes: Mode 1 (standard), Mode 2 (panning), and Mode 3 (erratic action).
