To adjust the focal length, rotate the zoom ring on the lens barrel. The lens offers a versatile range from 55mm for wider shots to 300mm for telephoto magnification. The zoom ring has markings for 55, 70, 100, 200, and 300mm to guide your selection.

3.2 Messa a fuoco
This lens utilizes a Smooth Autofocus Motor (SAM) for quiet and responsive autofocus. Ensure your camera's focus mode is set to autofocus (AF). For manual focusing, switch your camera to manual focus (MF) mode and rotate the focus ring on the lens.
3.3 Image Stabilization (Super SteadyShot®)
The Sony Alpha system DSLRs feature built-in Super SteadyShot® image stabilization. This system compensates for camera shake, which is particularly beneficial when using telephoto lenses or shooting in low light conditions. Ensure this feature is enabled in your camera settings for optimal results.
3.4 Lens Lock Switch
The lens is equipped with a lock switch to prevent the lens barrel from extending unintentionally during transport. To lock the lens, set it to the 55mm position and slide the lock switch. To unlock, slide the switch back.
