3. Operando a Lente
3.1 Zoom
To change the focal length, rotate the zoom ring on the lens barrel. The focal length markings (28mm, 35mm, 50mm, 70mm, 100mm, 135mm) are indicated on the ring. Rotate towards 28mm for a wider angle of view and towards 135mm for a telephoto perspective.
3.2 Focalização
This lens features both autofocus (AF) and manual focus (MF) capabilities. The Internal Focusing (IF) system ensures that the front of the lens does not rotate during focusing, which is beneficial when using polarizing filters.
- Foco automático (AF): Set the AF/MF switch on the lens (if present) or camera body to 'AF'. The camera will automatically focus when the shutter button is half-pressed.
- Foco manual (MF): Set the AF/MF switch to 'MF'. Rotate the focus ring on the lens barrel until the subject appears sharp in the viewlocalizador.
3.3 Função Macro
The lens offers a macro function for close-up photography. To engage the macro mode, typically you would zoom to the telephoto end (135mm) and then activate the macro switch or ring if available on the lens. Refer to your camera's manual for specific settings related to macro photography.
3.4 Controle de Abertura
The aperture (f/3.8-5.6) is controlled electronically by the camera body. Select your desired aperture setting through your camera's controls. The lens will communicate with the camera to set the appropriate aperture value.
4. Manutenção
4.1 Limpeza da Lente
- Elementos da lente: Use a lens blower brush to remove dust. For smudges or fingerprints, use a clean, soft lens cloth and a small amount of lens cleaning fluid. Apply fluid to the cloth, not directly to the lens. Wipe gently in a circular motion from the center outwards.
- Corpo da lente: Wipe the lens body with a soft, dry cloth. Do not use organic solvents like paint thinner or benzene.
