About the DZOFILM X-Tract 18-28mm T8 Probe Zoom Lens
Zoom Function

New form/category of macro shooting – zoom probe (18 – 28mm FF), covering the commonly used focal lengths of advertising/TVC, with a field of view of 100° – 73°, improving shooting flexibility, suppressing glare and vignetting outside the picture, and ensuring picture consistency.

Parfocal design, the focus remains unchanged during zooming, and a similar effect of Zouk’s zooming can be achieved.

Image Quality Performance

Constant maximum aperture T8, multi-layer anti-reflection coating, sharp and clear at full aperture.

Movie-level high-resolution image quality, 6 low-dispersion lenses correct colour, accurately restore colour, suppress breathing effect and vignetting.

Stability And Durability

Waterproof, dustproof and fog proof (IP57 protection, body waterproof length > 28cm, first lens with water anti-fog film), adaptable to harsh environments and special shooting.

Made of all metal (aerospace-grade aluminium alloy + oxide film, 25um thick), it ensures stability and durability in various complex shooting environments.

Lightweight And Convenient

The weight is only 1000g, the front diameter of the lens is < 30mm, and the possibility of shooting in a narrow space is good to avoid blocking light. The body volume is controlled at about 400mm in length, with a rear centre of gravity design to reduce shooting jitter and adapt to a variety of installation forms. Magnification And Focusing Capabilities Maximum 2.1:1 magnification, the closest focusing working distance is about 6mm. 300° focusing stroke helps to control the focus delicately and accurately, and has been verified by 100,000 high-frequency lifespans. Technical Features Of The Lens 7 high-refractive lenses, with a differential distribution of refractive indices of 2 + 5, make the picture more transparent and the colour temperature more realistic, improving the yellowing problem of traditional probes. Full tooth ring M0.8, adapted to the standardized design of the film and television industry. Accessories And Creative Design (BC Features) Self-developed OY-type support seat, quick-release O-type with 3/8 standard screw hole, Y-type with 1/4 standard screw hole, removable, convenient for adding accessories. MO.8 stepless rotating ring, 360-degree rotating shooting angle, with rotating scale mark, to achieve 0 displacement full-angle shooting. Usability Design From magnification, waterproof line to rotation scale, there are appearance prompts, and the operation is more humane and intuitive. A Bold Probing into Spectacular Marvels 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. Probe Zoom, A New Macro Perspective X-tract 18-28mm 0° T8 wide-angle probe zoom lens opens new dimensions in macro cinematography, offering greater creative flexibility and potential. Its full-frame design is compatible with Super 35 sensors, providing an equivalent focal length of approximately 22-35mm T8 in Arri Alexa 35 Open Gate mode, covering key focal lengths for commercial work. The probe’s zoom versatility allows flexible adjustments in tight spaces, enhancing spatial depth and perspective. With a constant aperture, it ensures consistent brightness across all focal lengths. Masterful Optical Balance for Immaculate Visuals 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 colour 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. Optimal Focus Control for Seamless Creativity The lens offers a smooth 300° focus throw, crafted with micron-level precision and tested for high-frequency durability. This ensures seamless focus transitions and enhanced depth of field control. The X-tract series probe zoom lens features a parfocal design that locks focus during zooming, maintaining sharpness even with subtle movements or rapid focal length changes, allowing for the classic Hitchcock dolly zoom effect in macro shots. Unmatched Breathing Control Beyond Primes 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. Ultra-Macro, Unlocking a New world 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. Ultimate Protection, Ready for Any Challenge Constructed from aerospace-grade aluminium 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. Agile and Flexible, Fully Controllable 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. Cine-standard Crafts, Precise and Reliable Its M0.8 gear pitch meets industry standards, making it compatible with most accessories and cine lens control systems. The dual-sided hydrophobic-coated UV filter and O-type quick-release clamp effectively protect the lens during specialized shoots, enhancing both stability and versatility. Manufactured with high-precision machining, the support incorporates a quick-release design for easy attachment. 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. Short Rear Design for Expanded Freedom 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.
