DULENS APO CAMBRIAN PRIME
In recent years, a growing number of camera manufacturers have ventured into designing and producing larger format cameras, catering to the evolving needs of filmmakers and cinematographers. However, these advanced machines often lack suitable lens options. Many rental houses have resorted to rehousing medium-format still photography lenses for use in cinema. While functional, these lenses typically feature smaller apertures and often fail to address critical issues such as color consistency across a set.
Recognizing this gap in the market, DULENS is proud to unveil a groundbreaking series of cinema lenses meticulously engineered for high-end medium format cameras, delivering unparalleled performance tailored to professional users.

Key Features:
Full Medium Format Coverage
Designed from the ground up to match the sensor sizes of today’s medium format cinema cameras, this lens series not only fully illuminates the sensor but also upholds an uncompromising standard of optical excellence. (Image circle covers the full sensor of Arri Alexa 65, which is the largest cinema camera sensor available in the market)
While being a medium-format lens series, APO CAMBRIAN PRIME can also be used on FF or S35 cameras, providing excellent performance just like our Mini Prime series.
Exceptional Optical Quality
Continuing our commitment to superior craftsmanship, this series features high-quality apochromatic (APO) spherical lenses. Designed with pure spherical optics, these lenses achieve advanced chromatic aberration correction while delivering a vintage-inspired aesthetic with exquisitely soft, creamy bokeh.
V+ Coating for Stylized Performance
Our proprietary V+ coating strikes a perfect balance between modern and retro aesthetics. This specialized coating ensures excellent micro-contrast, akin to multi-coated lenses, while preserving the gentle, nostalgic flare reminiscent of classic vintage glass.
Ultra Fast Aperture
Every key focal length in this set boasts an impressive aperture close to T2, empowering users to create with confidence in any lighting condition, from bright daylight to dimly lit scenes. (Normally, F2.8 T3 is already a fast aperture in the medium format world, even some premium F2 T2.2-T2.4 lenses, which only exist in standard focal lengths)
(Cambrain Prime has the same type of Mini Prime cat eye bokeh look )
Ultra-Compact Design
Staying true to DULENS’ signature philosophy of compact elegance, each lens in this series features a uniform front diameter of 80 mm. This lightweight construction aligns perfectly with the modern demand for portability and efficiency on set.
Unified Body Design
Focus and aperture rings are consistently positioned across all focal lengths, streamlining lens swaps and minimizing downtime for professional crews during fast-paced shoots.
Stylized Filter System
To enhance creative flexibility, we’ve developed an innovative filter system that allows users to switch between distinctive stylized looks effortlessly. Stay tuned for more details in our upcoming release announcements.
