I have a Minolta "Beercan" (70-210 f/4) and it's bizarrely developed fungus inside the "sealed" inner element assembly. I've taken it apart twice, cleaned it with detergent and ultrasonic on the small parts, and this is the third time it came back. I don't have the resources to un-epoxy (?) the sealed element and have gotten quoted of $150-200 locally. Is that pretty accurate?
And yes. I know this is a lot of nonsense for a lens that's now around $100 on the used market, but it's by far the best copy I've found - tack sharp wide open, little to no PF/CA, etc.
