Macro Probe Lens for Cinematography
The DZOFILM X-Tract 18-28mm T8 2.1x Macro Probe Lens is built for full-frame cinematography with a 43.2mm image circle. Its 18-28mm zoom range provides a 1.55x ratio for flexible macro compositions. The constant T8 aperture maintains consistent exposure throughout the zoom range, making it suitable for professional close-up work.
PL Mount Installation and Alignment
The lens uses a standard PL mount for secure attachment to compatible cinema cameras. A 360-degree rotating ring allows precise horizontal adjustment of the 90-degree optical path after mounting. The fixed right-angle tube design requires careful positioning on set to achieve the desired low-angle or tight-space perspective without obstruction.
Optical Constraints of the Probe Design
The 90-degree tube bends light at a right angle, limiting shooting to perpendicular perspectives relative to the lens barrel. The square front element with PET silver-coated reflective layer maximises transmission but fixes the optical path geometry. The T8-T45 aperture range controls depth of field and exposure, while the 26-element, 19-group construction corrects aberrations across the 22-35mm equivalent focal range in Arri Alexa 35 Open Gate mode.

Questions about this item
How do I verify the lens is performing as intended after mounting it on my camera?
Confirm the image circle covers 43.2mm, check that focus holds through the 18-28mm zoom, and verify consistent T8 brightness across the range.
What comes in the box and what must I source separately?
The lens with its fixed 90-degree tube and PL mount is supplied; camera body, follow-focus, matte box and any PL-mount accessories are not included.
Which version should I choose for full-frame versus Super 35 shooting?
