  2. Align the mounting index mark on the lens with the corresponding mark on your camera body.
  3. Insert the lens into the camera mount and turn it clockwise (for Nikon F-mount) until it clicks into place. Do not force the lens.

  2. While pressing the lens release button on the camera body, turn the lens counter-clockwise until it detaches.
  3. Immediately attach the rear lens cap to the lens and the body cap to the camera to protect them from dust.

Funcionamento da lente

Focalización

  • Enfoque automático (AF): Set your camera's focus mode to AF. The lens will automatically focus when the shutter button is half-pressed.
  • Enfoque manual (MF): Set your camera's focus mode to MF. Rotate the focus ring on the lens until your subject appears sharp in the viewfinder or on the LCD screen.

Zoom

Rotate the zoom ring to adjust the focal length between 28mm (wide-angle) and 80mm (telephoto). The current focal length is indicated by the markings on the lens barrel.

Using the Macro Function

To engage the macro function, slide the "NORMAL/MACRO" switch to the "MACRO" position. This allows for closer focusing distances and higher magnification, ideal for close-up photography. The macro feature is especially useful and easy to use, offering various magnifications simply by zooming in or out.

Nota: The macro function typically works best at specific focal lengths (e.g., 80mm) and may require manual focusing for precise results.

Control de apertura

This lens has a variable maximum aperture of F3.5 at 28mm and F5.6 at 80mm. The camera body controls the aperture setting. Refer to your camera's manual for details on adjusting aperture.

Mantemento e almacenamento

Limpeza da lente

  • Use un cepillo soprador para eliminar o po das superficies das lentes.
  • For smudges or fingerprints, use a clean, soft microfiber lens cloth and a small amount of lens cleaning fluid. Apply the fluid to the cloth, not directly to the lens.
  • Never use abrasive materials or strong chemical cleaners.

Almacenamento

  • Coloque sempre as tapas dianteira e traseira da lente cando non a estea a usar.
  • Store the lens in a dry, well-ventilated area, preferably in a lens case or bag to protect it from dust and physical damage.
