DZOFilm X-Tract 18–28 mm T8 90° Probe Zoom Lens

The DZOFilm X-Tract 18–28 mm T8 90° probe zoom lens brings a right-angle perspective to full-frame macro cinematography. Its slim 41.5 cm barrel and sub-30 mm front diameter enable probing into confined spaces, while a constant T8 aperture maintains consistent brightness across all focal lengths.

With a parfocal design and ≤ 0.5% focus breathing at 24 mm, the X-Tract delivers steady, high-precision focus shifts throughout the 18–28 mm range. A 360° rotating tip—featuring a square PET silver-coated front element—lets you pivot the optical path for unique angles, and a 300° focus throw offers cinematic manual control.
