I noticed my multi coated UV filters for my Contax G lenses have different colors. My newest have a deep green coating and some others (some are bought second hand) have a more blue color! What does this mean? Are the ones with the more blue coating deteriorated? Do I have to replace them with new filters? How bad is this? Is it still better then single coated filters?
I don't want to work with bad filters, but I don't want to replace filters that are actually still in good shape, so your input is appreciated!
