Enfoque, zoom y profundidad de campo

Antes de enfocar, gire el anillo del zoom 5para ajustar la distancia focal hasta que la composición deseada quede encuadrada en el visor.

Si su cámara cuenta con un botón o palanca de previsualización de profundidad de campo (reducción de apertura), podrá obtener la previsualización de la profundidad de campo a través del visor de la cámara.

Debido a las características ópticas de este objetivo, la distancia focal en las distancias de enfoque cortas se reduce sensiblemente.

La escala de distancia no indica la distancia precisa entre el sujeto y la cámara. Los valores son aproximados y deberían utilizarse exclusivamente como guía general. Cuando se tomen fotografías de paisajes lejanos, la profundidad de campo podría influir en el funcionamiento, de forma que es posible que la cámara realice el enfoque en una posición más cercana que el infinito.
