4.2 Aperture Control
The VILTROX 75mm f/1.2 lens offers a super large f/1.2 maximum aperture, ideal for low-light conditions and creating shallow depth of field. Aperture adjustment can be controlled in two ways:
- Automatic Control: Adjust the aperture directly through your camera body settings.
- Manual Control: Use the aperture ring on the lens barrel for direct adjustment. This is particularly useful for video shooting.
