DZOFilm Tango 18-90mm T2.9 S35 Zoom Lens (ARRI PL & Canon EF, Feet)

The DZOFilm Tango 18-90mm T2.9 S35 Zoom Lens (ARRI PL & Canon EF, Feet) combines cinema-grade optics with the operational flexibility of an ENG-inspired zoom. Its 5× focal range maintains a constant T2.9 maximum aperture from 18mm through 90mm, supporting consistent exposure as framing changes. A 16-blade iris, Super35 coverage, interchangeable ARRI PL and Canon EF mounts, and luminous focus markings in feet suit narrative, documentary, and live-production crews. For powered ENG-style operation, add a compatible MOVCAM servo sold separately.

The DZOFilm Tango DZO-T189029I is the feet / imperial-focus-scale edition of the 18–90mm Super35 cinema zoom. It has a 5× zoom range, a constant T2.9 maximum aperture through T22, a 31.5mm image circle, 24 optical elements in 17 groups, and a 16-blade iris. ARRI PL is the installed lens mount and an interchangeable Canon EF mount is included; only one mount can be fitted at a time. Minimum focus distance is 0.7m / 2ft 3in from the sensor plane. Manual ring rotations are 270° focus, 100° zoom, and approximately 74.1° iris. The front diameter is 114mm, the filter thread is M105, and the approximate lens weight is 3.54kg / 7.8 lb. The lens is parfocal by design with adjustable back focus, but requires proper calibration. It has no built-in stabilization or electronic lens communication, and the optional MOVCAM servo is not included.

The Tango 18–90mm is designed for Super35 / APS-C image capture with a 31.5mm image circle. It is not a native full-frame cinema zoom. When pairing it with a full-frame camera, verify a suitable Super35 crop or windowed recording mode and confirm the active sensor dimensions. The lens is supplied with an ARRI PL mount installed and an interchangeable Canon EF mount for cameras compatible with those mechanical interfaces. Check flange distance, lens clearance, back-focus calibration, lens support, and the camera's mounting requirements; do not assume the supplied EF mount adds electronic lens control. The approximately 3.54kg lens should be supported independently rather than relying on the camera mount alone.

A 24-element, 17-group optical construction is designed for consistent color, low chromatic aberration, and controlled distortion within the Tango family. The constant T2.9 aperture and 16-blade iris suit storytelling that moves between wide and portrait-style focal lengths without changing exposure settings solely because of zoom position. The minimum focus distance is 0.7m / 2ft 3in from the sensor plane, not the front of the lens. Manual focus rotates approximately 270°, zoom 100°, and iris 74.1°. Luminous scales, a 114mm front diameter, M105 filter threads, and 0.8 MOD rings help integrate the lens into professional cine rigs. Test back focus and focus tracking on the actual camera before critical zoom shots.
