تمرکز کول

This lens supports both autofocus (AF) and manual focus (MF). The focus mode switch is located on the side of the lens barrel.

• اتومات تمرکز (AF): Set the switch to 'AF'. The camera will automatically focus when the shutter button is half-pressed.
• لاسي تمرکز (MF): Set the switch to 'MF'. Rotate the focus ring on the lens barrel to achieve sharp focus. Use the camera's viewfinder or LCD screen to assist with focusing.

The minimum focusing distance for this lens is 15.7 inches (approximately 40 cm) across all focal lengths.

زوم کول

To change the focal length, rotate the zoom ring on the lens barrel. The lens offers a focal range from 28mm (wide-angle) to 70mm (short telephoto). The current focal length is indicated by markings on the lens barrel.

د یپرچر کنټرول

This lens features a constant maximum aperture of F2.8 throughout its zoom range. Aperture settings are controlled via the camera body. Refer to your camera's instruction manual for details on adjusting aperture.

د فلټرونو کارول

The lens incorporates helical focusing, which means the front lens barrel does not rotate during focusing. This design is convenient for using polarizing filters or other filters that require precise orientation.

ساتنه

د لینز پاکول

• د لینز له سطحو څخه د دوړو او نرمو ذراتو د لرې کولو لپاره د بلور برش څخه کار واخلئ.

• Never use abrasive materials, solvents, or household cleaners on the lens.

ذخیره کول

• کله چې لینز په کار نه وي، تل د مخکینۍ او شا لینز کیپونه ضمیمه کړئ.
• لینز په یخ او وچ ځای کې وساتئ، د مستقیم لمر وړانګو او سختې تودوخې څخه لرې.
• که چیرې د اوږدې مودې لپاره ذخیره کوئ، نو د فنګس د ودې مخنیوي لپاره د رطوبت کمولو اجنټ کارولو ته پام وکړئ.

د ستونزو حل کول

• د کیمرې لخوا نه پیژندل شوي لینزونه: Ensure the lens is securely attached and clicked into place. Turn the camera off and on again. Clean the electrical contacts on both the lens and camera body with a clean, dry cloth.

• انځورونه تیاره دي: Verify that the lens is properly focused. Check the camera's shutter speed to ensure it's fast enough to prevent motion blur, especially in low light or with moving subjects. Ensure the lens elements are clean.
