>>I think maybe I should have stopped working on the rear element group
>> about half an hour before I did. I had manged to get it looking quite
>> clear and the fungus which was between the layers had I thought receded,
>> but my wife reported that she could still see it, so I thought maybe a
>> little longer in the acetone would do the trick, unfortunately it seems
>> to have penetrated more into the glue between the layers so optically I
>> am back to where I was when I started.
>>
>>
>> The second element the single one, I managed to improve with some very
>> gentle rubbing with some hand creme (not ponds though). But you can
>> still see the remnants of the fungus on the lens which to my wifes eye
>> appears as watermarks.
>>
>> I am aware that this is a rare lens, however its real worth is now
>> debatable when compared against the two hundred dollar 8mm pelang and
>> now the new 8mm digital zuiko.
>>
>> The options now though are to repair the lens,
>>
>> 1. I could try contacting focal point (or can this be done by a list
>> member e.g John) and just ship them the rear elements to see if they
>> can repair them but it would be quicker if I could find a company in
>> switzerland or germany or even UK. Should I maybe ask at one of the
>> opticians here.
>>
>> 2. I could leave the rear group to soak overnight in acetone which I
>> am fairly confident will separate them - then get hold of some new
>> cement and try recementing, It the rotation as well as alignment
>> important. For the other element I could buy some ponds cream and try
>> again rubbing a little bit then cleaning it off, then a bit more etc so
>> I gently polish the surface, hopefully removing the marks.
>>
>> 3. I just leave it and put it all back together and use it.
>>
>> another thought but now I have the lenses in reasonable condition,
>> assuming they are separated could they not be measured by an optician or
>> their lab and then new ones made with equivalent strength and refractive
>> index etc, I am assuming technology has given us some benefit ;-) and
>> if one set can be made then two or more could be made to help the others
>> on the list - OR am I just looking at things far to simply.
