Description InfoSpecsFootageOn SetLens Test Dulens APO Cambrian Prime 40mm Dulens APO Cambrian Prime Lenses – A New Standard for Medium & Large Format Cinematography The Dulens APO Cambrian Primes are designed from the ground up for today’s large sensor cinema cameras. While cinematographers once relied on rehoused stills glass such as Mamiya Sekor, Dulens delivers a purpose-built cine lens series: modern, compact, and optically uncompromising. Covering sensors such as the Blackmagic URSA Cine 17K, the Fujifilm Eterna 55, and even the legendary ARRI Alexa 65, the Cambrian Primes unlock the full aesthetic potential of medium and large format cinematography. Key Features at a Glance Apochromatic design – virtually no chromatic aberration. No aspherical elements – smooth, onion-ring free bokeh and natural rendering. T2.0 aperture (≈ f/1.8) – exceptionally fast for medium format, fully usable wide open. Minimal vignetting on large format – even at T2.0, corners remain clean and sharp. Gentle coatings – low microcontrast with cinematic highlight roll-off. High MTF across the frame – edge-to-edge resolution without harshness. Cine-ready build – 270° focus throw, consistent gear positions, 80mm fronts. Compact & lightweight – around 700–850g per lens: remarkably small for medium format coverage. Matched set – consistent color, weight, and ergonomics across the entire range. Dulens Cambrian primes edge mtf What Makes Cambrian Primes Unique Unlike most modern cine lenses, the Cambrians avoid aspherical elements entirely. This prevents onion-skinning and harsh artifacts in bokeh, preserving a natural, cinematic defocus. They are also apochromatically corrected, eliminating chromatic aberration and delivering exceptionally clean color separation. Combined with gentle coatings, the lenses produce lower microcontrast and smooth highlight roll-off — technically pure yet never clinical. And while their rendering feels soft and organic, the Cambrians achieve a very high MTF index from corner to corner: detail, sharpness, and resolution across the entire frame. Superior to APO Mini Primes Compared to Dulens’ own APO Mini Primes, the Cambrians offer: Larger image circle for true medium and large format coverage. Less vignetting and fewer artifacts wide open. Higher resolving power and cleaner color rendition. Greater consistency across the set in mechanics and ergonomics. Complete Six-Lens Set All six focal lengths share identical mechanics for maximum efficiency: Focal lengths: 24mm, 32mm, 40mm, 55mm, 77mm, 105mm Aperture: T2.0 – T16 Focus rotation: 270° Front diameter: 80mm Filter thread: 72mm Iris blades: 11 Housing: consistent gear positions for focus & iris Close Focus & Weight Each lens is designed to be ultra-compact and lightweight, between 750g and 850g, making the Cambrians among the smallest true medium-format cine primes available. 24mm: close focus 0.19m (object) / 0.35m (image) – weight ~850g 32mm: close focus 0.20m / 0.35m – weight ~800g 40mm: close focus 0.27m / 0.42m – weight ~780g 55mm: close focus 0.36m / 0.51m – weight ~750g 77mm: close focus 0.53m / 0.68m – weight ~790g 105mm: close focus 0.70m / 0.85m – weight ~810g Optical Design 24mm: 14 elements in 10 groups 32mm: 14 elements in 12 groups 40mm: 13 elements in 10 groups 55mm: 11 elements in 10 groups 77mm: 11 elements in 8 groups 105mm: 10 elements in 7 groups Designed for the New Generation of Cameras The Cambrian Primes are not just full-frame capable; they are purpose-built for large-format workflows: Blackmagic URSA Cine 17K – coverage and sharpness across the oversized sensor. Fujifilm Eterna 55 – a true medium format cine camera, fully matched by Cambrian’s image circle. ARRI Alexa 65 – clean coverage even on the industry’s large-format reference. Even wide open at T2.0, the Cambrians show almost no vignetting or edge artifacts, making them uniquely reliable for high-resolution large-format capture. The Cambrian Look Natural skin tones with minimal grading effort. Smooth, artifact-free bokeh thanks to the absence of aspherics. Subtle flare characteristics that feel cinematic, not clinical. Gentle contrast with extremely high resolving power — a rare balance in modern glass. Conclusion The Dulens APO Cambrian Primes are: purpose-built for medium and large format, exceptionally small and lightweight, free of chromatic aberration and aspheric artifacts, and mechanically consistent across a six-lens set. For cinematographers seeking a modern alternative to rehoused vintage glass — with optical purity, compact form, and true large-format coverage — the Cambrians are the clear choice.
