Photographer Jason P. Odell looks at two different lens mount adapters to use Nikon lenses with Fujifilm X-mount bodies.
The Fotodiox adapter is an inexpensive, a no-frills option for mounting Nikon lenses to a Fuji mirrorless camera. It has a 4-position aperture ring that is compatible with Nikon G-type lenses.
The Metabones “Speed Booster” adapter is very expensive. However, it includes a glass lens element that offers a 0.71x crop factor, effectively restoring the full angle of view from Nikon FX lenses onto the Fuji APS-C format sensor. Along the way, the image circle is brightened, effectively increasing the lens speed by one stop.
