Hi John: Interesting lenses, the Breguetcameras people say they bought these prototypes from the Rollei Museum, they are probably talking about the Rollei museum pieces sold during the 1981 bankruptcy (some of them bought by the Braunschweig city Museum too) or perhaps about pieces from the new F&H GmbH bankruptcy during 2010. The Planar 135/2 never was built for the market; as the Planar 120/2 for the SL66, it had some problem for the lens performance. The difference between both lenses is that the Planar 120/2 for the SL66 is included in brochures, instructions manuals and books, it seems the Planar 135/2 for the SL35 does not appear mentioned in these media. Except for the Planar 135/2, the other lenses you mentioned below were manufactured for the market, they are included in several SL35 cameras lenses list and the manufacture time and specs and Voigtländer versions are mentioned in the Rollei Report IV.- Carlos 2011/1/3 John Wild <JWild@xxxxxxxxxxxxxxxxxxxxxx>: > ....some more for Carlos... > > Ebay 310275286226; 280567014243; 280598492763; 310276505259; 280567014254 > > John > > --- > Rollei List > > - Post to rollei_list@xxxxxxxxxxxxx > > - Subscribe at rollei_list-request@xxxxxxxxxxxxx with 'subscribe' > in the subject field OR by logging into www.freelists.org > > - Unsubscribe at rollei_list-request@xxxxxxxxxxxxx with > 'unsubscribe' in the subject field OR by logging into www.freelists.org > > - Online, searchable archives are available at > //www.freelists.org/archives/rollei_list > > --- Rollei List - Post to rollei_list@xxxxxxxxxxxxx - Subscribe at rollei_list-request@xxxxxxxxxxxxx with 'subscribe' in the subject field OR by logging into www.freelists.org - Unsubscribe at rollei_list-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field OR by logging into www.freelists.org - Online, searchable archives are available at //www.freelists.org/archives/rollei_list
