Metabones Speed Booster Ultra - Nikon G to E mount

This model is primarily designed for manual control and features a manual aperture ring; it is not intended to provide electronic autofocus for lenses.

While it can be mounted, this speed booster is specifically designed to optimize performance on APS-C (DX) sensors to reduce the crop factor. Using it on full-frame cameras may cause vignetting.

The adapter is constructed from high-quality brass and chrome for maximum durability and a secure fit.

Yes, the adapter is compatible with both Nikkor G lenses and standard F-mount lenses, including non-AI and AI manual focus lenses.

Yes, the tripod foot is detachable and natively compatible with Arca Swiss-style quick release systems.

Yes, the optical design increases the maximum aperture of your lens by 1 stop, allowing more light to reach the sensor.

Ensure the lens aperture ring on the adapter is set to the correct position and that you are aligning the mounting dots correctly without forcing the mechanism.

Check that the rear element of the adapter is clean and that the lens is fully seated and locked into the mount.

The aperture ring is designed for precision. Gently rotate it through its full range to ensure no debris is obstructing the mechanical movement.
