5. Obsługa obiektywu
5.1 Autofokus (AF)
The ZEISS Touit 2.8/12 lens features a fast and accurate autofocus system. Ensure your camera's focus mode is set to AF (Autofocus) for automatic focusing. The lens is designed for smooth and quiet operation, making it suitable for both photography and video recording.
5.2 Ręczne ustawianie ostrości (MF)
For precise control, switch your camera's focus mode to MF (Manual Focus). Rotate the focus ring on the lens barrel to adjust focus. Your camera's focus peaking and magnification features can assist in achieving critical focus.
5.3 Kontrola przysłony
The aperture (f/2.8 to f/22) can be controlled directly from your camera body. Adjusting the aperture changes the depth of field and the amount of light entering the lens. A wider aperture (smaller f-number like f/2.8) creates a shallower depth of field, ideal for isolating subjects. A narrower aperture (larger f-number like f/22) provides a greater depth of field, suitable for landscapes.
