DZOFilm X-Tract 18-28mm T8 FF Wide-Angle Probe Zoom 0-Degree Lens with 2.1x Magnification (Black)

The DZOFilm X-Tract 18-28mm T8 Full-Frame Wide-Angle Probe Zoom Lens boasts a slender design that allows it to easily access narrow, hidden spaces, capturing microscopic details invisible to the naked eye and transforming them into stunning imagery. The name 'X-tract' is inspired by the word 'extract,' meaning 'to draw out the essence.'

X-tract 18-28mm 0-degree 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. 

X-tract 18-28mm T8 0-degree 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. 

The lens offers a smooth 300-degree 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.

The X-tract series features native breath control, reducing breathing effects to just 0.5 percent at the 24mm (compared to 39.2 percent in other 24mm probe primes). With a relative illumination (RI) of 70.7 percent (vs. 54.9 percent in other 24mm probe primes), focus breathing becomes virtually imperceptible, minimizing the need for post-production adjustments. .

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. The minimum focusing distance is reduced from the traditional 56.3cm of probe lenses to 47.3cm, with a minimum working distance of just 6mm, 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 25 micrometer anodized coating enhances the body’s hardness, improving abrasion resistance and corrosion protection. Tested under extreme temperatures from minus 30-degree Celsius to 70-degree Celsius. 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.

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.
