Hi,
I recently acquired this lens: Mamiya - Sekor NB 90mm. There are fungus and dust in the lens.
I manage to dismantle the rear lens elements and clean the dust.
Here is the issues:
1) How to do dismantle the front element and clean it?
2) The ring to secure the lens to the body is taken off, How shall I put it back?
3) When the shutter is set at 1s, most of the time, it manage to close after 1s, but sometimes, it just stop responding. What should I do to ensure it behaves properly?
Hope someone is able to give me some pointer.
Regards.
