Discussion of the new nostalgic Trinovid made me aware of something I've never really understood. Zeiss and Leica both laid a huge bet on roof prisms in the early 1960s, and were surely aware of the image degradation they suffered from despite their high cost. Yet it took 25 years to develop phase correction coatings that would deliver image quality comparable to much cheaper porro binos... why? What was really so hard about it? That's a rather technical question, but does anyone here know?
(Somehow the gamble worked: enough people bought them for many years anyway... I gather that means image quality really isn't paramount for many people, even those who can afford Leica/Zeiss, despite all the nitpicking of alphas that goes on in some circles.)
