Hi. My yashicamat has developed haze on the internal face of the rear taking lens. I've got it out. It looks like a cemented doublet, but the haze is on the inside face - the haze looks like breath condensation, but it's fixed on the lens. I had hoped that it was simply lubricant evaporation, but it cannot be cleaned off with simple lens cleaning fluid and cloth. I've replaced the lens with another from a damaged yashicamat, but it has the start of gum separation around the perimeter. I'm hoping it will be ok at apertures smaller than f5.6. But back to the hazy lens: any suggestions as to how to proceed. My thoughts are to go thru the following steps: 1. Try 50:50 hydrogen peroxide/ammonia; 2. If unsuccessful, try pond's skin cream; 3. If unsuccessful, try cigarette ash (not sure how to do this); 4. Finally, cerium oxide, if I can get some. Any suggestions greatly appreciated. Regards, Arthur (apiarist1) -
