My impression was that apochromatic referred to a greater degree of color correction in a lens, and was an optical term, and that APO was just a shortened form of this. - -----Original Message----- From: Eric Welch <ewelch@ponyexpress.net> To: leica-users@mejac.palo-alto.ca.us <leica-users@mejac.palo-alto.ca.us> Date: Sunday, 09 November, 1997 2:17 AM Subject: Re: If Eric Says So At 10:35 AM 11/8/97 -0500, you wrote: >I do not know who has the trademark on 'APO' but I won't argue with either >Leica or Zeiss if they tell me it's theirs: they can hire more expensive >lawyers than can I! But lawyers aren't paid to get to the truth, just to beat the opposition into submission! :-) As for apo, maybe they didn't coin the phrase, but Zeiss made the first APO lenses for photography, so I'm told. Er, was that for microscopes? Maybe not photography, now that I think of it. I had an old girlfriend who did some study in the field of microscope optics. Maybe that's where I heard it. It's no big deal. The deal, here is that if Leica owns the term for purposes of trademark, then Minolta, Zeiss and a boatload of other lens manufacturers are breaking the law, or have licensed the term from them. I have my doubts. I'll bet it's the use of the term in context with other terms, like Telyt, or whatever. ========== Eric Welch St. Joseph, MO http://www.ponyexpress.net/~ewelch He, who will not reason, is a bigot; he, who cannot, is a fool; and he, who dares not, is a slave.
