Hi there. i just got a Canon 7 with 50/1.4 lens from my mother in law...🙂
She told me it was used quite a lot by her brother back in the 60's and 70's.
it's must have been sitting around in one of her closets for decades so there is quite some mold inside the lens. for the rest, the camera works fine. even the light meter seems to be in good working condition.
i'm quite new here (first post) so i'm just wondering if there is some place where i can send the camera to to have it cleaned. also the rangefinder needs to be aligned as it's not ligning up very well.
Can any 'decent' photostore clean this kind of lens or is there some specialist i can send the camera to? (maybe this has been discussed before, but as i said : me=newbie)
Also, how much would this cost me (more or less, from your experience) to have it completely cleaned and aligned?

thanks!

s.d.
 
From your mother in law....

If its from your mother in law, DAG is an excellent place to send your lens.😉
My canon 35mm was bought but Don did marvels cleaning it.
The 50 f/1.4 is an excellent lens BTW.

Enjoy..
 
what/where is DAG/Don?

(i'm on holiday at the moment in Toronto, but my home is in Shanghai... I suppose DAG/Don is in the U.S. do they send overseas...?)(guess i'd better ask them myself directly...)
thanks!

and i meant 50/1.8 lens, not 50/1.4... not that it matters

Excellent technician and very nice person to deal with.
His society name is DAG (His initials I guess)
 
If the lens has mold then it not worth send out for service but you can do it yourself. I have an instruction (large file) to clean it. Send me your email if you want it.
Ciao
 
The real issue, if it is truly mold, is that optical glass is relatively soft, the acid exuded by the mold etches the glass, removes any coating, etc., and usually, unless it is very recent, cannot be removed completely.

I use a repair service for some Leica stuff, etc., and I would guess $100 -$125 to do it.

And, depending on how bad it is Letien may be correct about its not being really worthwhile. But, it never hurts to have it checked by a competent tech, just to be sure. The problem is that it is impossible to tell how bad the damage is unless one simply goes ahead with having it disassembled and examined.

This is a real jerker, don't do it and you will never know, and there is the issue of a desire to keep old iron alive.
 
I just today picked up my Canon 50/1.2 from Essex Camera, where I'd taken it to have a bad case of fungus cleaned. Alas, they weren't able to do much to clear it up, so they didn't charge me even though they certainly went to some effort to try.
On a brighter note, my Canon 28/3.5 with a mild case of haze/fungus is pristine after a trip to Essex. 🙂
