4.2 Attaching the Lens Shade

The included lens shade helps to prevent stray light from entering the lens, reducing flare and ghosting, and also provides physical protection for the front element.

1. Align the index mark on the lens shade with the mark on the front of the lens.
2. Attach the lens shade by rotating it until it locks securely into place.

5. Utilizzo dell'obiettivo

5.1 Messa a fuoco automatica (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 Messa a fuoco manuale (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 Controllo dell'apertura

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.
