5. Instruccions de funcionament
Autofocus (AF) / Manual Focus (MF)
Use the AF/MF switch on the lens barrel to select your desired focus mode. In AF mode, the camera will automatically focus. In MF mode, rotate the focusing ring to adjust focus manually.
Focus-Range Limiter
This switch allows you to optimize autofocus speed by limiting the focus range. Select 'FULL' for subjects at any distance, or '∞-3m' to restrict focus to subjects further than 3 meters, which can be beneficial for distant subjects like wildlife or sports.
SteadyShot òptic (OSS)
The Optical SteadyShot feature helps to reduce camera shake, especially when shooting handheld at longer focal lengths or slower shutter speeds. Set the switch to 'ON' to activate stabilization. For optimal results, ensure your camera's in-body image stabilization (IBIS) settings are compatible or configured correctly.
OSS Mode Selection
The Mode switch allows you to select the appropriate stabilization mode:
- Mode 1: Estabilització general per a subjectes estàtics.
- Mode 2: Optimized for panning shots, stabilizing vertical movement while allowing horizontal movement for tracking subjects.
Botó de retenció del focus
Pressing this button will lock the current focus distance. This is useful for recomposing shots without losing focus on your subject.
Zoom Smoothness Adjuster
Rotate this ring to adjust the tension of the zooming mechanism. A 'SMOOTH' setting allows for easier, faster zooming, while a 'TIGHT' setting provides more resistance for precise adjustments and prevents zoom creep.
6. Manteniment
Proper maintenance ensures the longevity and performance of your lens:
- Neteja: Use a soft, lint-free cloth to clean the lens barrel. For lens elements, use a lens brush to remove dust, then gently wipe with a lens cleaning solution and a microfiber cloth. Avoid touching the lens elements with bare hands.
- Emmagatzematge: Store the lens in a cool, dry place away from direct sunlight and extreme temperatures. Use the provided lens caps to protect the front and rear elements.
- Resistència a la pols i la humitat: Tot i que la lent té un disseny resistent a la pols i la humitat, no és impermeable. Eviteu exposar-la a la pluja intensa o als ruixats d'aigua directes.
7. Solució De Problemes
Si teniu problemes amb la vostra lent, tingueu en compte els passos habituals següents per resoldre problemes:
- Lent no reconeguda per la càmera: Ensure the lens is securely mounted and clicked into place. Check for any debris on the lens or camera contacts.
- L'enfocament automàtic no funciona: Verify the AF/MF switch is set to AF. Check the Focus-Range Limiter setting. Ensure there is sufficient light for the camera's autofocus system.
- Imatges borroses: Check if Optical SteadyShot is enabled (if desired) and set to the correct mode. Ensure shutter speed is appropriate for the focal length and lighting conditions.
- Zoom ring too loose/tight: Adjust the Zoom Smoothness Adjuster to your preference.
For more complex issues, refer to your camera's instruction manual or contact Sony customer support.
