5. Impostazione

5.1 Montaggio dell'obiettivo

1. Rimuovere il tappo dell'obiettivo posteriore e il tappo del corpo della fotocamera.
2. Align the red index mark on the lens with the red index mark on your Canon EOS camera body.
3. Ruotare la lente in senso orario finché non scatta in posizione.
4. To detach, press the lens release button on the camera and turn the lens counter-clockwise.

5.2 Fissaggio a un treppiede o monopiede

Due to its weight (approximately 8.5 pounds), this lens should be supported by a sturdy tripod or monopod for optimal stability and image sharpness.

• Attach the lens's tripod collar foot directly to your tripod or monopod head.
• Ensure the tripod head is rated to support the combined weight of the lens and camera.
• The tripod collar allows you to rotate the camera and lens assembly for easy switching between horizontal and vertical orientations without removing it from the support.

6. Utilizzo dell'obiettivo

6.1 Messa a fuoco

• Messa a fuoco automatica (AF): Set the Focus Mode Switch to "AF". The Ring-type USM provides fast and quiet autofocus.
• Messa a fuoco manuale (MF): Set the Focus Mode Switch to "MF". Rotate the focus ring to adjust focus. Full-time manual focus is available even in AF mode by rotating the focus ring after autofocus has been achieved.
• Limitatore di messa a fuoco: Use the Focus Limiter switch to restrict the autofocus range. This can significantly speed up autofocus when you know your subject will be within a certain distance.

6.2 Stabilizzazione dell'immagine (IS)

The built-in Image Stabilizer helps reduce blur caused by camera shake, especially when shooting handheld or at slower shutter speeds.

• Interruttore ON/OFF: Turn IS "ON" for most shooting situations. Turn "OFF" when using a very sturdy tripod and fast shutter speeds to conserve battery power.
• Interruttore modalità IS:
  • MODO 1: Corregge le vibrazioni in tutte le direzioni. Adatto a soggetti fermi.
  • MODO 2: Corrects vertical vibrations during horizontal panning, and horizontal vibrations during vertical panning. Ideal for tracking moving subjects.
  • MODO 3: Stabilizes only during exposure. Useful for erratic movement or when you want to avoid IS interference during composition.

6.3 Using with Extenders (Teleconverters)

This lens is compatible with Canon EF 1.4x II/III and 2x II/III extenders to further increase focal length. Note that using an extender will reduce the effective maximum aperture and may affect autofocus performance.

• Attach the extender between the lens and the camera body.
• With a 1.4x extender, the focal length becomes 700mm and the maximum aperture becomes f/5.6.
• With a 2x extender, the focal length becomes 1000mm and the maximum aperture becomes f/8.
• Autofocus may be limited to the center AF point or may not function at all depending on the camera model and extender combination, especially at f/8.
