Rent NowSirui Night Walker 55mm T1.2 S35 Cine Lens (Sony E-Mount, Black)
The Sirui Night Walker 55mm T1.2 S35 is an ultra-fast, portrait-length prime cinema lens engineered natively for Sony E-mount Super35 and APS-C mirrorless sensor cameras. Boasting an incredible T1.2 maximum light transmission, this lens is a powerful creative asset for low-light cinematography, offering run-and-gun filmmakers immense exposure flexibility without forcing camera ISO levels into noisy thresholds. Packed with specialized Extra-Low Dispersion (ED) optics, minimal focus breathing, and industry-standard 0.8 MOD cine gearing, this lightweight aluminum prime delivers a beautiful shallow depth-of-field look with smooth subject separation, ideal for intimate close-ups and dramatic portraits.
CONDITION NOTE (INTERNAL FUNGUS ALERT)
Heavily Used / Budget Project Piece: This lens is being explicitly listed in Heavily Used condition due to an internal optical defect.
Cosmetic & Front Element Condition: Mechanically sound with a clean, well-maintained exterior barrel showing standard signs of handling. The front glass element is clear and free of scratches.
Internal Optical Condition: There is visible fungus growing inside the internal lens elements.
Real-World Impact: During real-world video testing, the fungus does not seem to noticeably degrade or show up in the image matrix when shooting wide open at T1.2. However, please note that it may cause soft contrast, ghosting, or visible artifacts as you stop down into more closed apertures (e.g., T5.6 to T16). This lens is sold strictly as-is—perfect for low-light specialty shooting, experimentation, or optical cleaning projects.
Ultrafast T1.2 Transmission & Portrait Compression
Ultrafast T1.2 Cinema Aperture: The light-gathering power of a true T1.2 rating permits cinematic exposure acquisition in exceptionally dim ambient lighting environments, yielding a razor-thin, dreamlike depth of field.
55mm Super35 Portrait Compression: Spans a portrait-length field of view on Super35/APS-C crop sensors (equivalent to approximately an 82.5mm lens in the full-frame format), naturally compressing backgrounds to heighten dramatic focus on character close-ups.
Premium Glass Formula: Employs advanced extra-low dispersion (ED) and high refractive index glass elements to mitigate chromatic aberrations, color fringing, and distortions, maintaining strong optical clarity across the image circle.
Minimized Focus Breathing: The internal optical tracking layout is heavily optimized to suppress focus breathing, preventing distracting frame magnification shifts when racking focus between foreground and background elements.
Unified Series Design & Professional Rigging
Consistent Night Walker Series Form: Shares the exact same physical lens dimensions, weight profile, and 0.8 MOD follow-focus gear ring spacing positions as the rest of the Sirui Night Walker series. This uniformity allows camera assistants to execute rapid lens swaps on rigs without needing to continuously reposition follow-focus units, wireless matte boxes, or iris drive motors.
Rigid Aluminum Alloy Chassis: Features a lightweight yet highly durable aluminum alloy housing that protects the internal optical element train during rugged field use.
Dual Focus Markings: The manual focus barrel features clearly engraved focus measurement reference markers displayed in both feet and meters for universal on-set pull ease.
