For both EF/FX and EF/GFX, followings were updated:
Nikon F Mount to Fujifilm GFX Smart AF Adapter Almost Here and Steelsring Smart Adapters EF/FX and EF/GFX Firmware 2.02/2.04
Nikon F to Fujifilm X Smart Adapter
Steelsring is about to release their Nikon F to Fujifilm GFX mount smart adapter. You can see the latest protoype in the image above. On their website here, they write:
Main features:
- Support Nikon AF-S G and E type lens, and AF-P G type lens contrast based AF in GFX 50s body.
- Electromagnetic diaphragm of type E Lens can be controlled by GFX 50s body, allows AF in full open ( decided by camera body ) and step down for exposure.
- Diaphragm of G type lens was manually controlled by aperture ring of adapter in real-time, so AF is conducted in real effective aperture as exposure. AF performance may be bad in low light/contrast, benefits are 1) Real aperture priority, 2) and totally no noise of consistent IRIS moving.
- Full EXIF info recording. ( For G type lens, only the current max open aperture was displayed and recorded, no way to adjust it ).
- Lens VR was support and effective on demand.
FX mount version adapter is in design phase, maybe with better performance of PDAF and auto aperture control version for your choice.
Note:
Support to AF-D type lens will be very limited, EXIF may works, but no AF absolutely.
Firmware Updates
Steelsring has a new firmware for the EF-FX and EF-GFX adapters.
