does anyone know if the fungus, which is on the shutter will effect my images. I doesn't appear to be on the glass. I could test it but for what the film cost, I'd rather ask first.
I agree and the fungus has spread right across the optic. It could have been cleaned off but they produce organic acids as they grow and, as well a degrading any coatings, these can etch the glass. Best to be rid of it I think.
