About Kinefinity EF 3 Lens Mount Adapter Combo

A revolutionary advancement in lens mounting technology, the Kinefinity EF 3 Lens Mount Adapter Combo is designed to enhance your shooting experience with MAVO and TERRA cameras. This innovative adapter is based on the active locking mechanism of the EF Mounting Adapter II but introduces significant improvements for seamless integration with traditional DSLR lens rotation methods.

The EF 3 Mounting Lens Adapter allows for quick and secure installation of EF lenses, utilizing a clockwise rotation similar to PL lenses. This feature is particularly beneficial for filmmakers using Follow Focus systems, ensuring stability and precision during shoots. The adapter is meticulously crafted to fit MAVO and TERRA cameras, providing a reliable connection for your lenses.

One of the standout features of this combo is the EF 3 Mounting Lens Adapter with e-ND (Electronic Neutral Density Filter). Unlike conventional ND filters that rely on rotating filter wheels or polarizing elements, the e-ND employs cutting-edge liquid crystal materials and electronic control. This technology offers a seamless exposure adjustment range from 0.6 to 2.1 (equivalent to 2 to 7 stops), maintaining sharp image quality and color fidelity without the drawbacks of traditional variable ND filters.

The e-ND's integration into the mounting adapter eliminates the need for external ND filters, filter holders, or matte boxes, significantly reducing the weight and complexity of your shooting setup. This makes it an ideal choice for solo filmmakers, documentary shoots, and challenging environments like polar regions. The adapter's electronic contacts allow for precise aperture control of EF lenses via the camera or SideGrip, enhancing operational efficiency.

Furthermore, the MAVO and TERRA cameras can automatically detect the e-ND and calibrate it to prevent any minor color shifts, ensuring consistent color accuracy across the entire tuning range. This automatic calibration feature is a significant advantage over traditional optical ND filters, which cannot communicate with the camera to adjust for color shifts.

The Kinefinity EF 3 Lens Mount Adapter Combo offers three distinct options to cater to various shooting scenarios: the regular EF mounting adapter without glass or filters, the new EF mounting adapter with e-ND, and the EF mounting adapter with KineEnhancer, which includes a 0.72 focal reducer and an extra stop for maximum iris.

In summary, the Kinefinity EF 3 Lens Mount Adapter Combo brings together optics and electronics in a compact, lightweight design, providing filmmakers with unparalleled flexibility and precision. Whether you're shooting in extreme conditions or require seamless exposure adjustments, this adapter combo is engineered to meet the demands of modern cinematography.
