کیمرے کی ترتیبات
Since this is a manual lens, you will need to adjust your camera settings:
- اپنا کیمرہ سیٹ کریں۔ دستی (M) or Aperture Priority (A) موڈ
- فعال کریں۔ "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" اور "Magnified View" features on your camera for easier manual focusing. Refer to your camera's manual for specific instructions on these features.

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.
دستی فوکسنگ
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.
- فوکس پیکنگ: Highlights in-focus areas with a colored outline.
- بڑھا ہوا View: Zooms in on a portion of the image for critical focus assessment.

لینز کی صفائی

- کھرچنے والے مواد یا سخت کیمیکلز کا استعمال نہ کریں۔
ذخیرہ
