This is for Canon FD/FL historians.
Anybody ever hear of a Canon FL-F 1000mm lens (note the "F" for fluorite)? I bought some circa-1970 Canon literature recently and noticed in the F-1 booklet (published June, 1971) a lengthy description of a new Canon 1000mm F5.6 Fluorite lens. Here's a direct quote from the booklet:
"The FL-F 1000mm F11 was newly added to the FL-F 300mm F5.6 and 500mm F5.6 series of lenses using artificial fluorite, greatly strengthening the applicability of this series of small size, high performance telephoto lenses. The FL-F 1000mm F11 has a very short overall length of 586mm compared to its focal length, and is a compact lens, approximately the size of a 600mm lens. The contribution of fluorite use is that it completely corrects for chromatic aberration. It makes elimination of the secondary spectrum easy and also makes the telephoto ratio small. The FL-F 1000mm embraces all of these features. Canon's high level of technology was acknowledged throughout the world when its conventional FL-F lens was awarded the 1969 Extraordinary Diploma of Honor by Interkamera in Hamburg."
To my knowledge, this lens was never produced. Wonder why they decided not to make it?

Olympus had prototype 800 and 1200 iirc that never got built, they did make an 1000 in 1972'ish but I've never seen one, perhaps it was develop as a spoiler to the imminent release of the OM1 system

It probably was cost. I wonder if the prototypes still exist or if they were sent to the crusher? Maybe one will pop up on eBay someday.
