Megadap ETZ21 firmware v2.04

1. Optimized the focusing performance of the zoom lens during continuous zooming, effectively improving the possible out-of-focus issue;
2. Resolved the compati​bility issue of the Viltrox AF85mm F2.0 STM ED IF lens with ZR camera bodies;
3. Enhanced the image stabilization performance of manual lenses: For manual lenses without electronic contacts, this update optimizes their image stabilization performance in stabilization mode.

The principle is as follows: Utilize the “Focus Ring Rotation Range” setting item in the Nikon camera menu, and match it with the actual focal length of the lens by setting the corresponding value — after the user completes the corresponding settings, the lens focal length information can be transmitted to the camera body through the adapter ring, realizing the coordinated work of the image stabilization function.

The specific operation steps are as follows: Enter the camera menu, select ” CUSTOM SETTINGS MENU” – “f Controls” – “f10 Focus Ring Rotation Range” in sequence.

By setting the value corresponding to the focal length, the image stab​ilization performance will be significantly optimized.

The corresponding values are as follows: Non-linear = 50mm 90° ≤ 14mm 120° = 20mm 150° = 25mm 180° = 30mm 210° = 35mm 240° = 40mm 270° = 45mm 300° = 60mm 330° = 70mm 360° = 80mm 540° = 85mm 720° = 95mm More ≥ 105mm
