Hi !
Someone has experience to disassemble trioplan 100 ?
My lens has "only" over 50 years, I'd like to clean inside dust (not much)
Is it easy operation (triplet lens) or need technical know-how ?
See this link: http://camerajunky.wordpress.com/2012/09/09/meyer-optik-gorlitz-trioplan-100mm-f2-8/
Another question, what product do you use to clean aluminum oxidation from silver barrel ?
My lens work fine, It is in VG conditions, but I'm thinking at a lifting
Regards

Don't do it, actually it is a high value lens, risky to clean if you need to ask how... and result will not better at all, dust harm only if fully cover lens surface makes less contrast and this lens has no high contrast anyway.
Try silver cleaning clothes , chemical to polish aluminium barrel , simple tooth paste , not jelly one works okay too. _________________ -------------------------------

Don't do it with a nice vintage lens, find a pro to do it.
If you want to learn how to do it, get some cheap mass produced lenses(Helios 44-2, FD 50/1.8......) take them apart, put them back together, if it still works and focuses properly then success! there are some threads which will help with tools etc... _________________ A Manual Focus Junky...

If you have zero experience: don't do it. Trioplan might be very easy to disassemble like the jupiters, but if not: you'll need some experience to open and especially close the lens properly (and collimation might be necessary). No problem on a cheap lens, but throwing a expensive lens away is bogus.
Aluminium oxidation: use lemon juice or any other (stronger) acid or just good old rubbing with toothpaste or silver/brass polish.
Good luck. _________________ Konica AR fan

The Trioplan is not easy at all. It has a screw you can't reach easily. The problem is you very easily can get the blades of the diaphragm out of their axles and if you did that you need to open it all up, including getting to this screw. You can not simply stop and get it back together from the point you didn't manage to go further.
@versanteest: Let it as it is, including the polishing. Do you have worms in your back?
@Dogtag: I don't even dare to correct you, after I read the OP's posting. Aluminium oxidation will best cleaned with strong alcali, not acid. I hope the OP don't apply this and destroy a fine lens. |

put into focus device a petrol drop , really only a drop, keep lens horizontal and rotate it, in lucky case old dry grease will melt a bit and don't go to glass! it will be better but risky. _________________ -------------------------------
