Dr Lieutenant Colonel Small <he grins broadly> offered: >>>Dear Dr Grant (hc) I realize that, after Mel Brooks, you are the oldest man alive on this Earth, and your opinions and thoughts are highly valued. But bear in mind that this is a LARGE group and includes folks with many, many interests. I am a "number-cruncher" and an analyst of optical history and lore. Hence, this discussion is of some interest to me, not just for its Leitz aspects but also for the broader question of the Zeiss and JSK and Rolleiflex and Pentax and so forth involvements. I certainly agree that the claims for the efficacy of lens coatings are a bit over-stated. In almost all conditions, a lens hood will do as much good. For that matter, most surveillance lenses, including those made by Leica, are uncoated. Let the guys talk on. It is of interest, at the least, to me, and I am always interested in determining shift-points in production technology. I would suspect that Leitz went to multi-coating on photo lenses from mid-1975 but I am hungry to learn more. My dear Dr Lieutenant Colonel Small <he grins broadly> I realize at times during techie discussions such as the "multi coating topic" I must annoy my fellow LUGGITES no end when I sound like a hard assed RSM (Regimental Sergeant Major) biting off a recruits butt. Therefore I offer an answer, good, bad or ugly to my sometime irrational responses. :-) My life career as a photographer has always been the end result image before me as slide or print! So far I think it's fair to say, without me knowing, nor ever having any interest in the mechanics and theories of "How it happens;" Other than my own physical ability to manipulate the shutter button at precisely the correct moment. And I feel I've not done too badly at this picture taking thing so far. :-) So when a topic, I realize of interest too many who are also talented photographers, but with a greater degree of interest in "How and Why" it happens, I do tend to lose it. I suppose it goes way back to my earliest times of constantly asking. "How does it do that????" About things photographic, when I was severely chastised by a grouchy old fart member of a camera club I briefly attended to learn more about photography. When one evening he loudly before the gathered group, offered: "YOU DON'T NEED TO KNOW ANY OF THAT STUFF! JUST TAKE THE DAMN PICTURES AND IF YOU DO THAT RIGHT YOU'LL DO FINE!!" I cringed before one and all and it ended any interest in things of "How and why does it do that?" But constantly about pressing the shutter release at precisely the right moment. Seemed fair enough so far. So now lads and lasses, you may understand why I become and sound like an old grouch when a topic is technical rather than the "look at this picture without knowing how it happened!" Thank you. Dr. Grant Naw it's still ted!
