Throwing this open to the forum to get a handle on the range, and share some images from the variable aperture AV-Xenotar . . .
Stop me if I'm wrong, but among the various Rollei projector lenses out there, we have:
1. Heidosmat 50+85mm f2.8 - 3 element, single-coated, plastic barrel (made by Rollei? Isco?)
2. Heidosmat 150mm f3.5 - 3 element, single-coated, plastic barrel (made by Rollei? Isco?)
3. Heidosmat 250mm f3 - X element, X-coated, X barrel (made by Rollei? Isco?) for Rollei P11
4. Heidosmat 400mm f4 - X element, X-coated, X barrel (made by Rollei? Isco?) for Rollei P11
5. S-Heidosmat: 85+90mm f2.8 - 3 or 4 element? (made by Rollei? Isco? Schneider?) Perhaps as Heidosmat but multicoated.
6. V/S Heidosmat 90/2.4 and 90/2.5 - 4 element - metal barrel (made by ?)
- 9 in total
7. Projar - 4 element Petzval - plastic barrel (made by Isco)
8. S-Projar 90/2.5 - 5 element - metal barrel (made by Schneider)
- 5 in total
9. AV-Xenotar - 5 element? - metal barrel (made by Schneider)
10. AV-Apogon - 5 element? metal barrel (made by ?)
- 7 in total
11. Vario-Heidosmat 70-120 - plastic barrel - X elements - made by X
12. Vario-Heidosmat 110-160 - plastic barrel - X elements - made by X
13. Vario Xenotar 70-120 - metal barrel - X elements - made by X
- 3 in total
plus various Curved Field and variable aperture versions (2 in total). Can anyone help fill in the blanks, make corrections?
Will shoot some images with the AV-Xenotar at different apertures next week to share.

According to my records (Rollei Report 4 by Claus Prochnow) there are 22 different Rollei projector lenses for formats up to 24x36mm, produced 1973 - 1981 by Rollei, Schneider and ISCO.

Thanks for that. Does Report 4 specify the construction and manufacturer of each lens?
The above list is already 26 unique models - perhaps some are earlier than 1973, or later than 1981?
But if Report 4 only counts 22 lenses up to 35mm we need to discount the longer AV Xenotars (90/2., 90/2.4-8 and Vario 110-160/3.5) fitted to medium format projectors. I think also the 150/2.8 HFT, which would bring us to 22. Then again, AV Apogons were designated for P66, too - so maybe not.

It answered some questions, and raised others. It's missing a few Rollei PJ lenses that I'm sure are pre-1998, as well as construction details (elements/groups). Great start, though.

You are welcome.
I've sent you the link for the 6x6 lenses as well.

That helps enormously - thanks. Rollei Report 4 still seems to miss the V/S Heidosmat 90/2.5, S-Heidosmat 90/2.8, Projar 180/3.5, Heidosmat 250/3 and 35+90mm AV-Apogons.
There's also a question mark over whether the Vario-Projar 70-120 (Cat. 979.410) is the same as the Vario-Heidosmat 70-120, which may also be missing.
Focusing on construction, can anyone confirm how many elements/groups have:
1. AV-Heidosmat 250/4.3
2. AV-Xenotar 60/2.8, 90mm f2.4 and f3.5 and 250/4
3. The Isco Heidosmats 110mm and 150mm (I believe shorter Heidosmats are 3-element and longer are 4-element). These fall in the middle . . .
4. S-Heidosmat 90/2.8
5. Any/all of the zoom lenses?
Completing that would close the book on Rollei PJ lenses. I'm happy to show the complete list if it's of interest.

Well, date of print was 1997. I have no idea when Rollei finally ceased production. Obviously it's only a marketing brand nowadays, similar to Voigtländer.
I've bought this book as it contains all camera lenses. I was never interested in projection lenses, that was just a lucky coincidence...

Sorry for the many pictures, and the variable quality: these are just some quick handheld shots on a gloomy day, but they show the drawing style, and how it alters (not much when stopped down)

and for comparison, the mighty Cabin 100/3.2

The 3D effect of the lens closed down is pretty spectacular! |
