I've heard a lot of discussion about the inconsistencies or evolution of iridium lenses through the years - but not so much about violet. I was wondering if anyone could speak of the differences of early violet and current violet lenses. Were the early violets more of a homogeneous violet or a stronger gradient from purple to blue? I know this is nitpicky discussion, but this is the OF after all - amirite? K. Readysetgo.
