Hello, Im looking for a bit of help with my shoe mount (Ef-42) with my Xt4. I seem to have lost the TTL option in my flash setting since attaching my new flash. I don't know if I've got the camera on a setting of some kind but whether the flash is mounted or not, I don't have TTL in my setting anymore - only M or off. Does anyone have any knowledge on what's happening? Thank you!

Hey I have recently attached my ef42 mount and now TTL has gone from my flash menu. Does anyone know why? Thanks in advance
