If you have any second thoughts I recommend taking your lens to a repair facility. They are simple in design and easy to restore. So far, I have restored two Mamiya TLR chrome shutter lenses and both are working fine now. Then use ROR with a t-shirt to remove any residues.

Clean with a lint free, chemical free (no anti static chemicals used in the dryer), white cotton t-shirt. It may require several times to completely remove the fungus. Tenth, use rubbing alcohol mentioned above with your finger tips (no fingernails, just skin) in a circular motion to remove fungus clouds from optical surfaces. Ninth, use ROR per the instructions to clean the optics, and do not use canned air. If you do this be sure to note on paper which side is up, in or out facing. A spanner wrench designed for lenses is required (see lesson 10) to remove the optical retaining rings that hold the individual elements. jewelers screwdrivers, needle nose tweezers, etc. For most repairs I have done only one screw has to be removed.Įighth, acquire the proper tools, i.e. Seventh, screws are tiny, and can be lost in a flash. Slightly bend the metal finger on the cam plate that engages the indents on the shutter selection ring. Sixth, if the shutter ring is sticky or the clicks indents are not "sharp", disassemble the two rings and clean them with isopropyl alcohol. Be sure to remove any lint left behind by the Q-tips prior to reassembly. Work the mechanism manually using the aperture selector arm, do not touch the blades with your fingers and use another Q-tip to remove excess and any grime.

To access the aperture internal assembly, This will require unscrewing the rear optical assembly. Check all screws for tightness.įourth, never use oil on any part of the shutter mechanism or ring assemblies or aperture assemblies.įifth, if the aperture blades mechanism is stuck or sticky, this can be cured using small amounts of 91% isopropyl rubbing alcohol applied with a damp Q-tip. This is located just south of the release lever mechanism. Third, if the shutter cocks but does not operate the blades when released a different screw is loose or has fallen out, that can be restored. This screw is located at the two O'clock position viewing the exposed taking lens shutter assembly straight on with upper rings and cam plate removed, viewing lens at 12 o'clock. Second, if the shutter will not cock the chances are a single screw has come loose within the shutter assembly that can be restored. There is no need to use a spanner wrench on the retaining clamps that secure the lens to the supporting frame. Front and rear optical assemblies unscrew. Should a part or screw fall out it will not go far and can be seen.įirst, do not remove the lens from the back plane frame, there is no need to access the lens from that side. Use a clean white towel on a well lighted table as your work area. Zero, before you start handling the lenses wash your hands. The usual disclaimer, use the lessons learned at your own risk.
