Tetapan Kamera
Since this is a manual lens, you will need to adjust your camera settings:
- Tetapkan kamera anda kepada Manual (M) or Keutamaan Apertur (A) mod.
- Dayakan "Release without lens" or "Shoot without lens" in your camera's menu, as the camera will not detect an electronic connection to the lens.
- Consider using "Focus Peaking" dan "Magnified View" features on your camera for easier manual focusing. Refer to your camera's manual for specific instructions on these features.
Mengendalikan Lensa
Melaraskan Aperture
The aperture is controlled directly on the lens using the aperture ring. Rotate the ring to select your desired f-stop. A wider aperture (smaller f-number like F1.8) allows more light and creates a shallower depth of field, ideal for portraits. A narrower aperture (larger f-number) allows less light and creates a deeper depth of field, suitable for landscapes.
Pemfokusan Manual
To focus, rotate the focus ring on the lens barrel until your subject appears sharp in the viewfinder or on the LCD screen. Utilize your camera's focus peaking and magnification features for precise focusing, especially at wider apertures.
- Fokus Puncak: Highlights in-focus areas with a colored outline.
- Dibesarkan View: Zooms in on a portion of the image for critical focus assessment.
Penyelenggaraan
Membersihkan Lensa
- Use a soft, lint-free microfiber cloth specifically designed for optical surfaces to clean the front and rear elements.
- For stubborn smudges, apply a small amount of lens cleaning solution to the cloth, not directly to the lens.
- Use a blower brush to remove dust particles before wiping to prevent scratching.
- Jangan sekali-kali menggunakan bahan yang kasar atau bahan kimia yang keras.
Penyimpanan
- Sentiasa pasangkan penutup kanta hadapan dan belakang apabila kanta tidak digunakan.
- Simpan kanta di tempat yang sejuk dan kering, jauh dari cahaya matahari langsung dan suhu yang melampau.
- If storing for extended periods, consider using a dehumidifying agent to prevent fungus growth.
