Hi rolleiman. As suggested by another poster I did the test against a light bulb and while no fungi or haze are present, some dust is present on the internal elements. Contrast seems to be quite fine anyway. Don't know about coating but, if present, it should be very "light". I'm used to more "modern" lenses from nikkor and the coloration given by the coating is very evident... so, I don't know about this lens, but I cannot recognize any color on the taking lens.
