Enfoque, zoom y profundidad de campo

Antes de enfocar, gire el anillo del zoom para ajustar la distancia focal hasta encuadrar la composición que desee. Si su cámara dispone de un botón o una palanca de vista previa de profundidad de campo (parada), puede previsualizar la profundidad de campo a través del visor de la cámara.

•Este objetivo dispone del sistema de enfoque interno (IF). A medida que disminuye la distancia de disparo, lo hace también la distancia focal.

•La escala de la distancias no indica la distancia exacta entre el sujeto y la cámara. Los valores son aproximados y solo deben emplearse como orientación general. Cuando se apunta a paisajes lejanos, la profundidad de campo puede influir en la operación y el sujeto puede aparecer enfocado en una posición más cercana que el infinito.

•Consulte en los cuadros de la página 144 los detalles de la profundidad de campo.

•Si el bloqueo del zoom está en la posición LOCK a una distancia focal de 28mm, el anillo del zoom se bloquea. Cuando transporte la cámara, bloquee el anillo del zoom para impedir que el objetivo se despliegue por su propio peso.

Ajuste de abertura

Utilice la cámara para ajustar el diafragma.

Aberturas máximas variables

Si con el objetivo se aplica un zoom de 28mm a 300mm se reduce la abertura máxima en 1 1/3 de parada. No obstante, no es necesario ajustar el diafragma para obtener una exposición correcta, ya que la cámara compensa automáticamente esta variable.
