Mamiya 6 50mm lens problem?

[steve521]

Hello everyone,

I am requesting some suggestions on a M6 50mm lens whose shutter does not fully open, this blades are shutter blades not aperture ones which are at the back. Please check the photo. Any suggestion how easy can this be fixed? I am based in London, anyone could give a sensible repair shop to deal with this kind of work?
The problem is less noticeable when aperture blade close down to 5.6, as the exposed shutter blade is overlapping with the aperture blade. This is a fantastic lens otherwise. Really annoyed by this.

Clean all your lens and body contacts. Check to see if this problem exists with the lens off the camera. Replace the batteries with fresh ones. The Mamiya 6 has some known issues of draining batteries though I've never seen this problem myself and I've had my current pair of batteries in my M6 for over a year.
Good luck and let us know what you come up with.
