The umbrella term for all camera optics – the optical system that focuses light onto the sensor and shapes the image. A fundamental element of composition.

What are Lenses?

Lenses (German: Objektive) are the optical system of a camera that focuses light onto the sensor and shapes the image. They determine focal length, aperture speed, sharpness characteristics, and rendering – fundamental elements of image creation in film.

From the crafts

Perspectives

Cinematographer

Objektive sind mein wichtigstes kreatives Werkzeug nach der Kamera selbst. Jedes Objektiv hat einen Charakter – ich wähle nicht nur eine Brennweite, sondern einen Look.

Director

Die Objektivwahl prägt den visuellen Stil eines Films fundamental. Weitwinkel für Intimität und Spannung, Tele für Distanz und Kompression – jede Entscheidung erzählt mit.

Producer

Objektiv-Sets sind oft der größte Equipment-Posten nach der Kamera. Die Wahl zwischen Miete und Kauf, zwischen Premium und Budget, beeinflusst das Budget erheblich.
