I purchased a legendary Biotar 75, my copy is postwar (year 1948) \"slim\" red T version of Biotar 7.5/1.5 with Exakta mount. Unfortunatelly the EXA-NEX didnŽt arrive yet so I tried the lens handholding on OM-NEX adapter with A7r II. I purchased the lens in Leica Vintage shop at Leica Vienna through the eBay, from first pictures there were some dirt on the rear element, so the lens was CLAŽd at Leica and they told me the lens elements are clear without fungus,haze,separation, etc. When the lens arrived I was surprised after closer check of the lens and taking some macro shots.. they \"forgot\" to tell me that there is coating defect, maybe fungus in this location,defect in cement. Price was 1200 EUR, I ask them for some partial refund about 300-400 EUR, because the resale value in the future is much lower, they offer only 100 EUR, so although the lens has nice rendering the question was to keep it or not. Finally I made a decision to return the lens. These pictures are wide open, slightly PPŽed.
