MY FISH EYE DOESNT WORK IN MF

MY FISH EYE ISNT WORKING ON MANUAL FOCUS...ANY TIPS ITS A TOKINA

I think we need more info to respond - what camera for a start?  Often AF lenses drive the focus electronically so could be an electrical fault.  Or if the command to go to MF comes from the camera it could be a dirty lens contact.

I would have thought AF would be preferable in any case as MF on ultra wides  can be a challenge.

Also, on the internet, using caps lock is basically shouting.
