I have read about removing coating on this board, but I would like to ask about this lens ..
The Elmar 50/2.8 is known for being hazy/foggy but I picked up a very cheap example the other day. A camera shop told me that the coating had deteriorated and it could be cleaned and re-coated for not too much money. I have no need for a soft focus lens so I am looking to have it cleaned.
The source of the problem is on the rear of the front element. Under a loupe the surface appears to be pitted with tiny holes. Is this the coating coming off? A swab with a Q-tip did nothing, obviously: the "haze" remains.
Is the only option a repolishing? I thought I would turn my inquiry over to the lens masters on this board. Any help or advice is welcome.
