 |
|
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 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 repaired a konica 75-150, with fungus in the internal surface of the last element (I dissambled it in the rear part from the last element to the diafragm and from the first element in the fornt of the lens). All was OK.

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)!!
Regards

This is a very good news, I thought before they are mostly un-reparable at home! Many thanks again!

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.

for stuck screws try neat wintergreen oil. that oil is the main ingredient of "Marvel Mystery Oil" a "Liquid Wrench" type penetrating oil; MMO works better than LW, and both those much better than WD40 imho.

Humm, I've got a Pangor 85-205/3.8 that's got heavy fungus and hazing on it. When I have time, I will try to take it apart? No guarantee that I can put it back together again. Anyone have a repair manual, where should I start, the front or the back?
