    Hello,

    in one of your lens reviews (the Takumar 85mm) you mentioned that you were planning to do a spectrograph measurement of different lenses to find out what the secret of some lenses regarding their colour rendition is. Did you ever do this test? As a fellow Pentaxonian ans physicist I would be interested in the results....

    Cheers, Steffen
