The name ‘X-tract’ is inspired by the word ‘extract,’ meaning ‘to draw out the essence.’ Its slender design allows it to easily access narrow, hidden spaces, capturing microscopic details invisible to the naked eye and transforming them into stunning imagery.
Combining a T8 large aperture, wide-angle zoom macro capabilities, and a spacecraft-inspired design, it redefines macro cinematography. The X-tract lens becomes a tool for exploration and discovery, extracting unique visual creativity from unknown dimensions and perspectives.
The X-tract 18-28mm T8 wide-angle probe zoom series redefines the possibilities of macro cinematography. Featuring a combination of 0° and 90° lenses, it offers boundless creative flexibility. Designed for full-frame, it is fully compatible with S35 formats, providing an equivalent 22-35mm T8 range in Arri Alexa 35 Open Gate mode, ideal for commercial filmmaking. The 0° and 90° probe zoom lenses allow effortless adjustment of focal length and perspectives, even in confined spaces, creating enhanced spatial depth and dimensionality. This flexibility empowers filmmakers with exceptional adaptability and creative expression.
The interchangeable front module offers 0° (direct view) and 90° (right-angle) options, covering 95% of probe lens shooting angles. The 90° tube features a 360° rotating ring for flexible horizontal adjustments, while the right-angle design enhances camera movement flexibility and framing options, unlocking endless macro creativity with adjustable focal lengths.
As the first T8 90° probe lens, it incorporates a newly designed square front element to improve the RI (relative illumination) and reduce light loss. The simplified prism structure and PET silver-coated reflective layer enhance reflectivity, ensuring a constant T8 aperture and consistent brightness across all focal lengths.
Note: Images captured with the 90° angle lens require mirror correction.
X-tract 18-28mm T8 0° lens features 7 high-refractive-index (HRI) lenses and 6 extra-low-dispersion (ED) lenses, striking an optimal balance between size and weight while minimizing chromatic aberrations, distortions, and optical flaws common in probe lenses. Its innovative differential distribution of HRI lens delivers prime-level image quality and accurate color temperature, effectively reducing the yellowish tint commonly seen in other probe lenses. Distortion is kept within ±2% across the entire zoom range, with near-zero distortion and focus breathing at 24mm, ensuring precise rendering of intricate micro-details.
The combination of prism structure and 360° rotating ring, offering an additional dimension for creative adjustments and providing a more immersive macro experience. The entire series features a smooth 300° focus throw, tested for high-frequency durability and micron-level assembly precision, enabling precise focus shifts and more flexible depth of field control. The X-tract lenses feature a par-focal design, locking the focus during zooming. Whether capturing subtle movements or quickly changing focal lengths, the focus remains sharp, delivering the classic Hitchcock dolly zoom effect even in macro shooting.
The X-tract series features native breath control, reducing breathing effects to just 0.5% at the 24mm (compared to 39.2% in other 24mm probe primes). With a relative illumination (RI) of 70.7% (vs. 54.9% in other 24mm probe primes), focus breathing becomes virtually imperceptible, minimizing the need for post-production adjustments. This ensures seamless visual continuity and stability during focus shifts, delivering immersive and spectacular cinematic visuals.

With a maximum magnification ratio of 2.1:1, the X-tract reveals the intricate textures of everyday objects and creates stunning, highly detailed visuals. When capturing tiny objects like insect wings, water droplets, sand grains, and miniature items, it brings out microscopic structures that are often invisible to the naked eye. The minimum focusing distance is reduced from the traditional 56.3cm (1’11”) of probe lenses to 47.3cm (1’6″), with a minimum working distance of just 6mm (0.2″), allowing the lens to almost touch the subject for finer macro details.

Constructed from aerospace-grade aluminum alloy, the lens is lightweight yet robust. A 25μm anodized coating enhances the body’s hardness, improving abrasion resistance and corrosion protection. Tested under extreme temperatures from -30°C to 70°C, it ensures stability and durability in challenging shooting environments. With IP57-rated dust and water resistance, the lens body is waterproof to over 28 cm. The front lens element features a hydrophobic anti-fog coating, reducing water and fog accumulation for consistently clear imagery.

Weighing just 1.09 kg, with a length of 41.5 cm and a front diameter of only 29.6 mm, the lens offers smooth operation in narrow spaces such as between book pages or inside miniature models. It provides greater flexibility and compatibility compared to larger macro setups.The rear-heavy design shifts the lens’ balance closer to the camera body, making it easier to maintain stability on tripods, sliders, stabilizers or MOCO, reducing shake and enabling precise focus and zoom adjustments. When used with sliders or robotic arms for large-range movements, it offers superior control precision, minimizing post-production adjustments.

With a 28cm water immersion depth, dual-sided hydrophobic coated UV filter, and O-type quick-release clamp, the lens ensures stability and versatility during challenging shoots.
The 90° right-angle probe lens features a 360° rotating ring, ensuring seamless compatibility with professional cinema equipment and accessories. Optional follow-focus accessories effectively manage rotational focus adjustments. The rotating ring allows for easy adjustment of the lens angle, enabling quick correction of the frame’s horizontal alignment to ensure precise composition. Clear markings for magnification ratio, waterproof lines, and rotation scales on the lens body further improve usability, offering filmmakers a seamless and intuitive shooting experience.
The X-tract Series reimagines versatility with a next-generation short rear design. The native PL mount features rear elements that protrude just 1.37 cm from the mounting flange. This short rear protrusion is compatible with DZOFILM Octopus and most PL-E/RF/LPL adapters and Speedboosters, enabling larger apertures and a wider FOV to meet high-speed shooting needs, providing users with greater creative flexibility. *Note: Interchangeable EF mounts will be available soon.
