(ps, they've made hassy distagons at 50/2.8 and 40/4, not sure about 40/2.8. Zeiss have also just announced a Distagon 50/1.4 for Canikon, making it a retrofocus distagon apparently makes it better than a normal planar).
I think i've read about Zeiss saying something to that effect. Can't find the original wording now, but it was something along the lines of, "yes, we can make faster, but we don't, we'd rather make high IQ"Originally Posted by David Lyga
It could work in the same way as the SWC, no mirror. If it was made for NASA it was probably made for either astronauts taking shots of earth from space, or taking night-shots of skies. Either way, it could have been built as an aerial camera, fixed hyperfocal so no need to focus.Originally Posted by AgX
