4.1 Auto Focus (AF) / Manual Focus (MF) Switch
The lens features a switch on its barrel to toggle between Auto Focus (AF) and Manual Focus (MF) modes. This allows you to choose the focusing method best suited for your shooting situation.
- AF (ໂຟກັສອັດຕະໂນມັດ): In this mode, the camera's autofocus system will automatically focus the lens. This is suitable for most general photography.
- MF (Manual Focus): In this mode, you manually rotate the focusing ring on the lens to achieve focus. This is useful for precise focusing in specific scenarios like macro photography, astrophotography, or when the autofocus struggles in low light.

The aperture (F2.8) is controlled electronically through your camera body. Refer to your camera's instruction manual for details on how to adjust the aperture settings.
4.3 Built-in Lens Hood
The lens features a built-in petal-shaped lens hood. This hood helps to reduce flare and ghosting caused by stray light entering the lens, improving image contrast and color saturation. It also provides some physical protection to the front element.
