Scherpstellen, zoomen en scherptediepte

Voordat u kunt scherpstellen, draait u de zoomring 5 om de brandpuntsafstand aan te passen totdat de gewenste compositie wordt weergegeven in de beeldzoeker.

Indien uw camera beschikt over een voorbeeldknop of -hendel (stop-beneden), kunt u de scherptediepte zien door de zoeker van de camera.

Wegens de optische eigenschappen van dit objectief wordt de brandpuntsafstand iets kleiner bij kleinere scherpstelafstanden.

De afstandsschaal geeft niet de exacte afstand weer tussen het onderwerp en de camera. Waarden zijn benaderingen en dienen enkel als algemene referentie. Bij het fotograferen van landschappen kan de velddiepte de werking beïnvloeden waardoor de camera mogelijk op een punt scherpstelt dat dichterbij ligt dan oneindig.
