Canon EOS 5 Analogue Camera - Focusing problem

[salmon22]

Hello my Canon EOS 5 has an autofocus problem in which the subject that I want to focus on is completely blurry and the camera focuses at the back. At first I thought it was the lens however I have tried many different eos lenses and the problem persists.

Manual focus works.

Also strangely complete automatic mode works but I want to have control over aperture and exposure.

What could be the problem here? And would it be worth to get it repaired?

Are the images blurry or just the viewfinder? Could the diopter be off?

Does the EOS5 have multiple, selectable focus points?
