EF Mount Adapter w/ e-ND

Bring Optics and Electronic into One

The Mounting adapter with Built-in Electronic ND (e-ND) employs high-precision hybrid of liquid crystal material, optics and electronic technology. It covers the widest range from 0.6 to 3.3 (2 stops to 10 stops).

At the same time, it remains consistent color accuracy over such wide range when working with TERRA.

Integrate e-ND into mounting adapter, it means no optical ND filter needed in front of lenses, therefore no need of filter holder or even matte box, which reduces loads of shooting system greatly: more compact and lightweight, and also smoother operating. So it is very good for one-man band, documentary shots, shooting at harsh environments, like North and South Polar areas.

 

Color Accuracy over Whole Range

More importantly, TERRA can sense the e-ND and calibrate it over potential minor color shift automatically, as soon as the mounting adapter with e-ND being attached to TERRA. Then no matter monitoring or recorded footages, TERRA can always maintain color accuracy over the whole tuning range from 0.6 to 3.0.

For optical ND or other glass ND, camera can not detect or get any information from ND glass, and there is no way for the camera to calibrate color shift that ND introduces. However, for mounting adapter with e-ND, TERRA can detect the e-ND automatically, and get the status of e-ND on every slight adjustment operation on e-ND, and then calibrate any potential minor color shift based on the data received. Don’t worry about the color effect when using e-ND on TERRA, let cinematographers focus on shooting.

 

Attention:

• For mounting adapter with e-ND, it can not be set to Clear, so you need to have a regular mounting adapter for low-light conditions or in-door case.
• For mounting adapter with e-ND, when shooting on some very special liquid crystal materials, the image may show some inevitable color shift;
• The surface of e-ND is AR-coated glass. You could clean it with much care. Any glass damage or scratches are out of warranty.
