    Interview with the new head of Zeiss Sports Optics

    Thanks for the nice summary David :t: Perhaps I should have charged more for my work! :-O Chosun :gh:

    Interview with the new head of Zeiss Sports Optics

    Not necessarily - sure you probably get the best HT bang for the buck in the prisms, but the HT glass range covers the full gamut - flints, crowns, various grades suitable for prisms - there's 12 different products last time I looked at the Schott catalogue. They could go anywhere or nearly...

    Interview with the new head of Zeiss Sports Optics

    LOL ! :-O I'm quite a fan of fresh shaved leg ham off the bone - it's a very very light pinkish colour. If it was much older (but not yet moldy) it would be a more greyish colour. That's what I see - very very slight light pinkish grey with a hint of greenish. Some others see it too. It fits...

    Interview with the new head of Zeiss Sports Optics

    As far as I can tell you've just effectively agreed with everything I said. As well as the slightly longer optical path through the A-K prisms, note they are also physically much longer which would require stronger refractive lenses throughout the optical train or again suffer greater...

    Interview with the new head of Zeiss Sports Optics

    Lee, I just checked the Australian Zeiss website too, and it is no help in clarifying matters - there is no mention of any HT glass, and they mention "multiple" fluoride lenses (meaning more than 1 but we really don't know how many). As far as the "green ham" goes - it's more 'ham' than...

    Interview with the new head of Zeiss Sports Optics

    Actually, I don't think that's the case as the extra length of the A-K prisms would make for a faster focal ratio which would increase aberrations (CA, etc) if the physical length of the binocular stayed the same. It would also muck up the Centre of Mass and reduce the effect of the touted...

    Interview with the new head of Zeiss Sports Optics

    Thanks Vespo, That's interesting. If that is correct (and I'm still not discounting a mix-up) , it could be as little as 1 HT lens in the eyepiece .... I would estimate that the transmission benefit of a HT A-K prism v's a non-HT S-P prism at the daylight and night time wavelengths at about...

    Interview with the new head of Zeiss Sports Optics

    LOL :-O that's interesting! :t: Mostly I have used "several" to mean 4, and distinguish it from a "few" which I have taken to be exactly 3. For me 7 or 8 would be something more like "stacks", and I would think 10-12 would be getting more toward "bucketloads" :) :-O Chosun :gh:

    Interview with the new head of Zeiss Sports Optics

    Lee, Further to what we have spoken about, I wonder if something hasn't been lost in translation leading to the incorrect story? It wouldn't surprise me at all if those within Zeiss are talking apples and pears either. The Schott HT range of glass is a specific range of glass (12 types at last...
