Schneider AV-Xenotar HFT 1:2.8 150mm lens 4 Rollei P66/Rolleivision 66 projector

This is the latest Schneider lens, the AV-Xenotar HFT 1:2.8 150mm for medium format projection. The Xenotar lens works fine on the latter models (starting with the P66 (P66E, P66A, P66S), basically on all halogen lamp models including the Rolleivision 66 Dual P) but it bottoms out if you try to project on a screen larger than 6' (72"X72") on the P11.0 model. Rare, of course. It sold for $500 at online discount stores around year 2000 (probably over $1000 nowadays, adjusted for inflation). Normal throw so it is fine for home projection or a large screen in a larger venue (conference room, classroom). Generally recognized as the finest lens in medium format slide projection (it was also used, in a different mount, for 6X7 projection (by Goetschmann, Liesegang).
