I found one of my lens rear glass have some fog like blur, I guess it might well be fungus, do you guys know if it can be cleaned? Or Leica will replace this piece of glass?

 

Anyone have this type service done? Approx cost ?

 

Thanks

I think that you will find a thread explaining that Leica no longer deal with fungus. You will need to talk to an independent repairer and I doubt that you will get a cost before the lens has been examined as cost will depend on how much dismantling is required and how significant the fungus is, if that is it is actually fungus. If I were you I would look through the list of repairers on this forum and contact whoever is close to ask directly.

That is a job for a third party repair service. most likely it is haze which will clean off.

Thanks, I have one lens the focus tab is quite stiff, should I just turning back forth few more time or I should actually send it to Leica?

 

Btw looks haze, so is it haze consider as fungus?

No it is not. Fungus is often characterized by spots or branch-like structures, As long as it has not etched into the coating and/or the glass it can be cleaned off as well.

But I repeat, In general I would not consider Leica CS the best venue to send it to. For well-known repairpersons CLA-ing older lenses is daily work, Leica is more into repairing more recent models nowadays, although they will of course accept such repairs as far as possible. But not fungus.

In the US both DAG Camera Repair (Don Goldberg) and Sherry Krauter routinely clean haze from Leica lenses. Both have been very quick on job like this, and do excellent work.

Thanks, I have my local people have looked at it, it seems the rear group which 2glasses glued group glue went bad and moisture went in need to replace it and as well as front element. Anyone have experience on replace glasses inside the lens? And how much you have paid?

Ah -separation. If you are  very lucky it sometimes works to separate the lenses completely and reglue them. If you have to replace both front and rear (are the parts still available?) it probably won't come cheap and you will have lost the matching that Leica used to optimize the lens. Depending on the value of the lens it might be a writeoff.

Hi Jaapv, can you please elaborate more on matching the glasses?  I thought leica can either replace with parts in inventory, or just make new piece of glass by previous spec, and put on it. but it seems doesn't work that way by your saying.   thanks

Making new glass is VERY VERY expensive and time consuming....it is not done one lens at a time, as the proper glass components have to be batch measured, heated, cooled, ground, coated, etc.
