1. Focus Mode Switch (AF/MF)

The lens features a switch on the barrel to select between Autofocus (AF) and Manual Focus (MF) modes. Slide the switch to your desired mode.

• اي ايف (آٽو فوڪس): The camera will automatically focus on your subject. This mode is ideal for most shooting situations.
• ايم ايف (مينوئل فوڪس): Allows you to manually adjust the focus by rotating the focus ring on the lens. This is useful for precise focusing in specific scenarios or when autofocus struggles.

2. Aperture Control

The lens features an aperture ring for direct control over the aperture setting. You can choose between F2.0 (wide open) to F16. The wider aperture (smaller f-number) allows more light and creates a shallower depth of field (more background blur), while a narrower aperture (larger f-number) allows less light and creates a deeper depth of field (more in focus).

سار سنڀال

1. لينس صاف ڪرڻ

• Use a soft, lint-free cloth or a lens brush to remove dust from the lens surfaces.
• For smudges or fingerprints, apply a small amount of lens cleaning solution to a microfiber cloth and gently wipe the lens in a circular motion.
• Avoid touching the glass elements directly with your fingers.

2. اسٽوريج

• Always attach both front and rear lens caps when the lens is not in use.
• لينس کي ٿڌي، سڪل جاءِ تي، سڌي سج جي روشني ۽ انتهائي گرمي پد کان پري رکو.
• جيڪڏهن گهڻي وقت تائين ذخيرو ڪري رهيا آهيو، ته پوءِ ڦڦڙن جي واڌ کي روڪڻ لاءِ ڊيهوميڊائيفائنگ ڪيبينيٽ يا سليڪا جيل پيڪٽ استعمال ڪرڻ تي غور ڪريو.

مشڪلاتون

1. Autofocus Issues in Low Light

In very low light conditions, the autofocus system may struggle to acquire focus. This is a common characteristic of many lenses and camera systems.

• حل: Switch to Manual Focus (MF) mode and adjust focus manually.
• حل: Use an external light source to illuminate your subject, aiding the autofocus system.
• حل: Ensure your camera's firmware and the lens's firmware (if applicable) are up to date, as updates can sometimes improve autofocus performance.

2. Vignetting at Wide Apertures

Some vignetting (darkening of the image corners) may be noticeable at wider apertures (e.g., F2.0 to F4). This can be a creative effect for portraits but can also be corrected.

• حل: Stop down the aperture to a narrower setting (e.g., F5.6 or higher) to reduce vignetting.
• حل: Vignetting can often be corrected in post-processing software using lens profiles or manual adjustments.
