Autofocus (AF) Operation:

The VILTROX AF 15mm F1.7 E lens features a fast and quiet STM autofocus motor. To use autofocus, ensure your camera's focus mode is set to AF. The lens will automatically adjust focus based on your camera's settings (e.g., single-shot AF, continuous AF, wide-area AF).

Manual Focus (MF) Operation:

To use manual focus, set your camera's focus mode to MF. Rotate the focus ring on the lens barrel to adjust focus. Your camera's focus peaking and magnification features can assist in achieving precise manual focus.

ການຄວບຄຸມ Aperture:

The lens features a bright f/1.7 maximum aperture. Aperture can be controlled via your camera's settings, allowing you to adjust depth of field and light intake. The wide aperture is particularly useful for creating shallow depth of field effects (bokeh) and shooting in low-light conditions.
