Using manual (adapted) lenses is great on a Fujifilm X. I have a set of Canon FD Macro lenses that are terrific.
At first you might have issues as the shutter doesn’t fire when such lens is on the camera. The camera thinks you don’t have a lens and therefor prevents you from firing the shutter. You need to enable “Shoot without lens”. It’s in the manual but not explicitely explain, and it’s inconsistent depending on the camera model. As I have both a X-Pro1 and an X-T3, this confused me as I couldn’t find it on the X-T3.
Fotodiox, who sells mount adapters, has you covered in their help guide. But really Fujifilm, couldn’t you at least be consistent? It’s not even “later models changed it”. X-Pro2 does it differently from the X-Pro1 and X-Pro3.
Here are some instructions:
Allow shooting without lens
On the Fujifilm X-Pro1:
1. Press the button. Go to the 3rd page of the Shooting Menu:
2. Select Shoot without lens:
3. Make sure it is on:
On the Fujifilm X-T3:
1. Press the button. Go to the Setup menu:
2. Select Button/Dial Setting:
3. On the second page, select Shoot without lens to be on:
Setting the focal length
Optionally, you should set the lens focal length. This helps the camera deciding shutter speed and others, and also this get added to the Exif meta data.
On the Fujifilm X-Pro1:
1. Go to the same Shooting Setting menu page 3 and select Mount Adaptor Setting:
2. Select a lens:
3. If you need to change the focal length select Focal Length Setting:
4. Set the focal length:
On the Fujifilm X-T3:
1. Go to the Shooting Setting menu:
2. Go to the second page select Mount Adaptor Settings:
3. Select one of the 6 focal lengths:
4. If you need to change it, select Focal Length Setting and set the focal length:
You should now be set. Remember if you use a different lens to set the focal length. You don’t need to reset the Shoot without lens to off for use in other cases.
