5.3 Camera Settings for Manual Lenses

• Go to your camera's menu.
• Navigate to the custom functions or setup menu.
• Enable the setting for "Release shutter without lens" or "Shoot without lens". The exact wording may vary by camera model.
• Set your camera to Manual (M) mode for full control over exposure.

6. Operating the Lens

6.1 Manual Focusing

This lens features manual focus only. To achieve sharp focus:

1. Look through your camera's viewfinder or LCD screen.
2. Rotate the focus ring until your subject appears sharp.
3. Utilize your camera's focus peaking or magnification assist features for precise focusing, especially at wide apertures like F0.95.

6.2 Adjusting Aperture

The aperture controls the amount of light entering the lens and the depth of field. To adjust the aperture:

1. Rotate the aperture ring on the lens barrel to your desired f-stop (from F0.95 to F16).
2. The aperture ring is clickless, allowing for smooth, stepless adjustments, which is beneficial for video recording.
