Thanks Rob for your consideration. Well this may be interesting, but it depends on the costs of the coating. A nice copy of the pre-war CZJ Sonnar currently costs about 300-350 USD on ebay, often less. So if the coating will cost me the same amount, I wouldn't do it but rather look for a nice copy of the Opton-Sonnar "T"
