1. Focal length & field of view It offers a zoom range of 55 mm to 210 mm, which on APS‑C (crop sensor) bodies gives an equivalent of about 82.5 mm to 315 mm in 35 mm terms 2. Aperture (maximum & minimum) The maximum aperture is variable: f/4.5 at 55 mmand f/6.3 at 210 mm. The minimum aperture ranges between f/22 and f/32 depending on zoom position. 3. Image stabilization (OSS) It has built‑in Optical SteadyShot (OSS) to help reduce blur from camera shake, especially useful at longer focal lengths or in lower light. 4. Optical construction & aberration correction The lens is built with 13 elements in 9 groups, including ED (Extra‑Low Dispersion) glass elements and aspherical elements, to help control chromatic aberrations, distortion, and maintain image clarity. 5.Focusing & close distance / magnification** The minimum focusing distance** is **1.0 m (3.28 ft)** throughout the zoom range. Maximum magnification is ~**0.23× (≈ 1:4.35)** The lens uses an **internal focus mechanism**, so the barrel does not extend during focusing which helps with handling.
