I wish to collect here what lenses are not cleanable at home ,because you need to face to face that kind of technical difficulties what is not resolvable at home.
All zooms - they have difficult constructions.Personally I can't open and rebuild when I tried one. Any other opinion ?
Konica Hexanon 135mm f3.5 AR - it has glued elements if you have trouble between this tags that is not resolvable.
Vivitar Series 1 28mm f1.9 37xxx it has glued elements you can't open it.
Kaleinar 2.8/100 glued elements you can't open it. _________________ -------------------------------

I have cleaned a zoom - a Quantaray 28-80 for Olympus that was apparently wet at a beach, which I got for free.
Luckily the optics were only dirty on the outside.
I disassembled partially and cleaned out sand from the mechanism and the front and back elements. It seems to work OK now.
I have a Zeiss 40/4.5 that looks terrible just now, it looks like sand is stuck on the lens. Lets see if I can fix this. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |

I think I'll try to open up my fungused yashica 75-150 zoom when I have time. It has no value anyway, so it will be good "training" for cleaning fungus. |

I have repaired several zooms, each tends to be a bit special
- rebuilt a Tamron 28-80 SP with replacement plastic bearings on the zoom cams, which got rid of the loose motion,
- rebuilt a Tamron 35-210 SP which had liquid damage,
- repaired a sticky diaphragm on a Tamron 60-300 SP.
The hardest one was a Tokina 80-200 f2.8, with a separated element in the second zoom group - I had to dismantle the lens to the point where I could extract the element, then split the components with methylene chloride, then re-cement with UV-curing optical adhesive - the results look reasonable so far.
It all depends on how determined you are (and how much you love to tinker with things)!!

I have tried to open it but the screws are too tight :/ i managed to unscrew the inner screws that hold some diaphragm levers but i probaly don't need to unscrew them anyway, it's the outer screws (bayonet mount) that i need to unscrew first. And they're too tight :/ i'm starting to wear out the shape in the screws. I've thought that maybe glueing the screwdriver with epoxy may help. Any ideas? even destructive ones... i can put new screws i don't care if I destroy them. |

Sounds interesting ... Can you share more about how to unglue the elements and where to get the optical adhesive? |

Today i talked to a lens repairer and he has heard that some of his old collegues (pity is that he dead several years ago) you could 'cook' the glued lenses in oil (around 200C ) and then the lenses would seperate after some time. Then he used Canadian Tree Balsam to glue the lens element back.
Anyone knows more about this method? |

I've heard of it. Supposedly, it only works for older lenses cemented with organic glues. I would warn against using Canadian Tree Balsam though: fungi lust love it. _________________ List of lenses |

Yes Alex -- this is not a problem at BUT ..
the main problem is VACUUM - why?
Small article of dust or anything like that -- and you can start your heating process again
You need vacuum tunnel ..

I don't have anything to do on a Sat afternoon. I figured I would take the Pangor 85-205/3.8 apart and see if I could learn more about taking lenses apart and put them back together again. I started at the back, cleaned, ok. The the front, cleaned, ok. When I had the front off, peering into the zooming elements it was heavily fogged/fungused. Took the front zoom element group out, as suspected it's fogging due to delamanation ( I can see the rainbow lines on the edges ). I realized that when putting it back together again, the rear tube and M42 mount could be used to adapt to other longer lenses so I took all the elements out and am reusing the back as an extension tube with a manual aperture Old lenses are good for something! _________________ Wilson

Yesterday I searched for experiments a lens with a fungus etched lens, that could not be removed with normal ways.
I found my old Tokina 60-300/4.0-5.6 zoom lens - my first lens with fungus.
I rememberd, that I could not clean the fungus there.
And after I opend the front lens, I rechognized why: The front lens element is in a cell that seems like one could not open without damaging. And the fungus is inside.
Interesting thing about it: Looks like a lens group that is glued together - but I thin that lens was produced ~ 1988. I thik it was not with canada balsam, but with synthetic glue. It is my first lens where I found the fungus inside. _________________ Camera modification, repair and DIY - some links to look through: http://www.4photos.de/camera-diy/index-en.html

I've cleaned and totally dissasembled three series one 70-210, first one is mine and the other two i sold, everything worked perfect (took me a while but it worked)
Also a vivitar series 1 35-80 nikon mount that worked perfect. I repaired a copule more zoom but I can´t remember them now.
Right now i have a series 1 28-90 that is only bolts and pieces and can even remeber how to put everything back togheter (focusing helicoid was broken and I am waiting to get hold of another one to repair it) and is only collecting dust on my desk.
My first zoom was a nikon 28-70 AF, it is istill in the drawer, never managed to put the helicoid back again, maybe i will give it a go again now that I have more experience.
I think that fungus between glued elements i the only thing that cant be repaired relatively easy at home. |
