Take your cinematography further with this Laowa OOOM 25-100mm T2.9 Cine Lens Bundle from Venus Optics, which includes the OOOM zoom lens and its vintage look, a 1.33x rear anamorphic adapter for creating widescreen images on a 16:9 sensor, and a 1.4x full-frame expander that enables using the Super35 zoom lens with full-frame sensors without vignetting. The zoom lens comes with an interchangeable PL mount, though the anamorphic adapter and full-frame expander are in PL mount only.

The rear anamorphic is lighter than a front anamorphic element and helps create natural-looking flares, keeping the look of the OOOM lens without introducing the strong "anamorphic lens flare" look to your images. Five shims are included with the bundle for critical flange focal distance adjustment. The 1.4x full-frame expander maintains the image characteristics of your OOOM lens without degrading the image, and it loses only one stop of light while expanding the lens coverage to cover full-frame sensors. The 1.4x expander converts your lens to a 35 to 140mm T4 to T32 zoom lens.

Zoom Lens

  • The lens has been designed to produce images with color and contrast reminiscent of vintage lenses, as opposed to the cold, clinical look of many modern-day lenses
  • The lens covers a 33mm image circle throughout its zoom range, covering larger Super35 sensors and enabling you to use the lens to capture higher-resolution images on cameras with larger Super35 sensors
  • The lens is parfocal, allowing the focus to remain constant throughout the zoom range
  • Minimal focus breathing as you adjust the focus
  • Cine-standard focus, iris, and zoom lens rings allow you to use industry-standard lens control systems such as follow focus units and lens control systems
  • The attached PL mount can be easily swapped out for the included E and EF mounts
  • The lens has a 95mm front filter thread and a 100mm front (includes a 100 to 114mm step-up ring for compatibility with a wider selection of matte boxes)

1.33x Rear Anamorphic Adapter
