۲.۲ د لینز جلا کول

1. ډاډ ترلاسه کړئ چې کیمره بنده ده.
2. د کیمرې په بدن کې د لینز خوشې کولو تڼۍ فشارولو پرمهال، لینز د ساعت په مقابل لوري وګرځوئ تر هغه چې ودریږي.
3. د کیمرې څخه لینز لرې کړئ.
4. Attach the rear lens cap to the lens and the body cap to the camera to protect them from dust and damage.

۵.۲ د لینز هود نښلول

The lens hood helps to block extraneous light and reduce flare. Align the lens hood with the front of the lens and twist until it locks into place. For storage, the hood can be reversed and attached to the lens.

3.4 Using the Tripod Collar

The lens includes a removable tripod collar for better balance when mounted on a tripod, especially given the lens's weight. Loosen the knob on the collar to rotate the lens for vertical or horizontal shooting, or to remove the collar entirely.

4. عملیات

4.1 Autofocus (AF) and Manual Focus (MF)

The lens features a switch to select between Autofocus (AF) and Manual Focus (MF) modes. In AF mode, the Hypersonic Motor (HSM) provides fast and quiet focusing. Full-time manual focus override is available, allowing you to fine-tune focus manually even when in AF mode by simply turning the focus ring.

4.2 Optical Stabilizer (OS)

The Optical Stabilizer (OS) function helps to reduce camera shake, especially useful in low light or when shooting at longer focal lengths. The OS switch allows you to turn the stabilization ON or OFF. This lens offers two OS modes:

• حالت 1 (نورمال): For general shooting, compensating for vertical and horizontal camera shake.
• Mode 2 (Panning): For tracking moving subjects horizontally, compensating only for vertical camera shake.

یادونه:

• Turn the OS OFF when using a tripod to prevent potential image blur.
• The OS may produce a slight sound during operation; this is normal.

4.3 زوم کول

Rotate the zoom ring to adjust the focal length between 70mm and 200mm. The internal zooming mechanism ensures the lens length remains constant.

4.4 Using with APS-C Cameras

When used with APS-C (crop sensor) cameras, the effective focal length will be approximately 105-300mm (depending on the camera's crop factor). This provides an even greater telephoto reach.

۶.۴ د ټیلیکون کنورټرونو سره کارول

This lens is compatible with Sigma APO teleconverters (sold separately) to further extend its focal length. Refer to the teleconverter's manual for specific attachment and usage instructions.

5. ساتنه

۴.۱ د لینز پاکول

• د لینز له سطحې څخه د دوړو لرې کولو لپاره د بلور برش وکاروئ.
• د داغونو یا د ګوتو د نښو لپاره، د لینز پاکولو محلول سره یوځای د پاک، نرم مایکرو فایبر ټوکر څخه کار واخلئ چې په ځانګړي ډول د آپټیکس لپاره ډیزاین شوی.
• Never use harsh chemicals or abrasive materials on the lens elements or body.

5.2 ذخیره کول

• کله چې نه کارول کیږي، 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 او فنګس د مخنیوي لپاره د وچولو مایع کارولو په اړه فکر وکړئ.
