6. Kushandisa Lenzi

6.1 Manual Focus

This is a manual focus lens. To achieve sharp images, rotate the focus ring on the lens barrel until your subject appears clear in the viewfinder or on the camera's LCD screen. For fisheye lenses, a common technique is to set the focus to a specific distance (e.g., 1 meter or 3 feet) and rely on the extensive depth of field to keep most of the scene in focus, especially at smaller apertures.

6.2 Aperture Control

The lens features an aperture ring on the barrel. To control the aperture directly from your camera body (if supported), set the lens's aperture ring to its smallest aperture value (f/22). This allows the camera to electronically control the aperture setting. If your camera does not support electronic aperture control with this lens, you will need to adjust the aperture manually using the ring on the lens.

6.3 Exposure Settings

Since this is a manual lens, you may need to set your camera to Manual (M) or Aperture Priority (Av/A) mode. In Manual mode, you control both aperture (via the lens ring or camera, as described above) and shutter speed. In Aperture Priority mode, you set the aperture, and the camera automatically selects the appropriate shutter speed.
