Designed for cinematographers, DoPs, filmmakers, rental houses, and film schools, the Aureus line delivers professional-level optics, zero focus breathing, and full-frame coverage with exceptional sharpness and consistency.

How is AUREUS PRIME different from the ATHENA PRIME series?

AUREUS PRIME is not an upgrade or replacement for ATHENA PRIME but is positioned as a higher-tier companion.

What makes the T1.4 aperture so significant in the AUREUS series?

The ultra-fast T1.4 aperture provides greater control over depth of field, superior low-light performance, and soft, cinematic bokeh—especially notable in wide-angle lenses like the 18mm. It enables filmmakers to achieve a dimensional, immersive look even in challenging lighting conditions.
