This lens features an AF/MF switch on the barrel. Slide the switch to 'AF' for autofocus operation, allowing the camera to automatically focus on your subject. Slide it to 'MF' for manual focus, enabling precise focus adjustments using the focus ring.
2. Чоңойтуу
The zoom ring is located towards the front of the lens barrel. Rotate the zoom ring to adjust the focal length between 24mm (wide-angle) and 70mm (telephoto). The focal length markings are clearly indicated on the lens.
3. Диафрагманы башкаруу
The lens features a constant maximum aperture of F2.8 across the entire zoom range. Aperture can be controlled via your camera body's settings. This wide aperture is ideal for low-light conditions and achieving shallow depth of field.

To clean the lens surface, use a soft, lint-free cloth specifically designed for optical surfaces. For stubborn smudges, a small amount of lens cleaning solution applied to the cloth (not directly to the lens) can be used. Avoid touching the glass elements with your fingers.
2. Сактоо
When not in use, always attach the front and rear lens caps. Store the lens in its provided case or a dry, cool place away from direct sunlight and extreme temperatures. Avoid storing the lens in areas with high humidity to prevent mold growth.
3. Экологиялык эске алуулар
