About Love

Filmed by Kanamé Onoyama

Director Interview

Love is a universal theme, yet it takes countless forms. In this project, I aimed to capture its essence through a sequence of short, emotionally impactful scenes within a five-minute film. This was more than just a lens performance test—it was an exploration of how the lens would resonate with human emotions. Love is complex. It can be passionate, familial, platonic, unfulfilled, or even transform into hatred or jealousy. This film weaved together these different facets, challenging the Sigma Aizu Prime Line to capture the subtlest nuances of human emotion.

This project was to balance cinematic beauty with the realism of improvised performances. The primary shooting style was handheld, with other styles selectively used where needed. Having the Sony Venice 2 as a main camera, for travel sequences, the Sony FX3 allowed for spontaneous filming without special permits, making full use of natural light and ambient sound for immersive storytelling.
The crew was kept to a taxi-sized team, with additional assistants or technicians brought in only for larger equipment needs. This approach ensured efficiency while capturing a wide variety of locations and subjects in a short time.
