The T1.3 aperture enables exceptionally shallow depth of field and graceful bokeh, seamlessly separating the subject while preserving a natural sense of depth and dimensionality. This refined visual language draws the viewer into the frame with a subtle yet powerful presence.
Optical design for the demands of cinema
All lenses in the Aizu Prime lineup feature an optical system developed exclusively for cinema applications. While maintaining modern sharpness, they avoid rigid or harsh depictions—delivering a natural, organic look. They provide quiet elegance and depth to the image, with distortion and focus breathing carefully minimized to ensure visual consistency, even in dynamic scenes.
Huge perspective range coverage
The Aizu Prime Line is designed as a system to cover a wide range of focal lengths from 18mm to 125mm. Following the 8 lenses released in 2025, three more lenses—21mm, 100mm, and 125mm—are now being released, bringing the lineup to 11 lenses spanning ultra-wide-angle to telephoto. This comprehensive system is adaptable to diverse scenes and compositions, and supports a wide array of visual expressions.
Completely consistent look
