8. No lookup, I'd venture perspective control, but that's only for wide angles.

"C" doesn't mean apo, and I don't recall any lens that has no focusing helicals, like the Hasselblad 135mm (bellows only).

It's not "C" mount, because I actually have a Nikon F to C-mount (little video camera) adapter.

And that's all I can guess without cheating.

Looks like you stumped the band. I have all the old brochures but don't recall this.

But you never know. Having had a friend who worked in a camera store, I got a 500 mm f/5 "cat" that is not formally listed in my old literature.

I had a second busy day in a row today, so I may go through my living camera history museum a bit later tonight.
