2012/9/26 Marc James Small <marcsmall@xxxxxxxxxxx>: > Carlos, you have me confused. The 2.8/150 JSK Xenotar is a medium-format > lens, not a large-format design. Was it ever used on a LF camera? > Enquiring minds want to know! Marc: The regular 2,8/150 Xenotar (to mark a difference with the Aero Xenotar prototype) is suitable for MF and for the 4x5" size within the Large Format according the Schneider specs for the lens, it is a heavy lens with a Size 3 shutter and used for the 4x5" format very much, it is very appreciated for this LF due to the high correction and lens speed, BTW it can be used with solid and robust MF cameras with superb results, these are the Schneider specs in German, English and French for several MF and LF lenses: http://www.schneiderkreuznach.com/archiv/pdf/objektive_kompl.pdf Carlos --- 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
