MTL's weak spot was the shutter wind ribbon and the plastic meter gears used for the meter movement.
The shutter ribbon has adjustment but even if you set at shortest length, the shutter still did not charge. They used to supply different lengths of this charge ribbon ( made of spring metal.)
I did not like to work on these models as they usually stopped working right after the repair was done and usually I had to re-work on the camera at least two times.
The lens, however, was excellent.
