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 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.
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.
