Postavke kamere

- Postavite kameru na Priručnik (M) or Prioritet otvora blende (A) način rada.
- Omogući "Release without lens" or "Shoot without lens" in your camera's menu, as the camera will not detect an electronic connection to the lens.

Upravljanje objektivom
Podešavanje otvora blende
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.
Ručno fokusiranje
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 Peaking: Highlights in-focus areas with a colored outline.
- Uvećano View: Zooms in on a portion of the image for critical focus assessment.
Održavanje
Čišćenje sočiva
- Use a soft, lint-free microfiber cloth specifically designed for optical surfaces to clean the front and rear elements.
