Thank you for your reply.
I think that between 80mm. and 180mm. is a gap and I am trying to fill it. And I would like to have a medium tele-photo lens for travelling, the 2,8/180 mm. is too heavy. I cannot find an AF version of the 150mm. for more than 2 years. That is why I wonder if the lens hit the market and available.
It looks that the same lens is called either Tele-Xenar, or Xenotar 4/150.
The Russian dealer has the AF Tele-Xenar 4/150 mm HFT PQS in the price list for years. I have the Rolleiflex 2006 brochure with the AF Tele-Xenar lens listed. On the other hand, the Michael's Hy6 review mentions an AF version of the Tele-Xenotar 150mm. lens. It is confusing.
Thank you and king regards,
Yes, there is a Schneider AF Tele-Xenar 4/150mm PQS (1/1000).
