looking for a non functionnal Olympus SZH body

#1 Post by Milou » Thu Dec 02, 2021 9:31 am

Hello,

If anybody has an Olympus SZH body (or even a szh-10 one!) with damage to the zoom mechanism or any ohter mechanical part and therefore unusable, I would be interested to get if at least the 2 bottom lenses are clean :wink:
In fact, only this black metal plate with 2 lenses (just above objective) would be useful for me, in order to replace mine with 2 damaged lenses (see pictures).....

cleaning them with various chemicals (also for fungus) didn't change anything. i think their coating is damaged.......
But the SZH objective with is below these lenses is in very good condition. Only these 2 bottom lenses are damaged in this body!

Thank you for your help

alcohol - ether, alcohol isopropylic, F petrol and also for fungus : ammonia and hydrogen peroxide.....
No result after that!

I you consider them “total loss” try polishing them with Brasso copper polish and an old cotton Tx-shirt.
Will remove any coating so a bit loss of contrast, but reasonable chance you are able to get the thing working again.

Those solvents that you used are not strong. Try xylene first.

If xylene does not work (which indicates the residues on the lenses may be solidified metal fume), try polishing with very fine polishing grit or tootch paste.

Attempting to repolish the lenses is likely to be a nightmare all its own imo.

I'm with sabatini on this one, a bit of pitch on a stick, some cerium oxide, and a little time. The trick is to keep the lap moving in random motions and to rotate the lens to avoid polishing zones into it. Any coating will be lost and either need to be reapplied of accepted without.
I've polished minor flaws out of telescope mirrors and a couple of leses. It doesn't always work out, but if the lens is a total loss anyhow there's not much to lose. I've also ground major dings out of two mirrors, but at that point you're really just grinding a new mirror with a pre-formed blank.
