He also has some very interesting pages about rare soviets. Since he's friend of Dr. Mladek, he has access to rare birds. Take a look on this page http://www.marcocavina.com/articoli_tecnici_fotografici.htm and look for the word "sovietici" (Ctrl+F), you will find some interesting articles
Guido	Posted - Aug 05 2018 : 08:30:04 AM Hi all By the way there is a 24mm Macro lens on Kickstarter now with an opticaly very similar construction like the Zeiss JO-1: https://www.kickstarter.com/projects/laowa/revolutionize-macro-videography-laowa-24mm-f-14-pr?ref=epdhdr http://www.ussrphoto.com/UserContent/582018_8b57eb50abc7d59e6292c472fc45a307.jpg Best wishes - Guido
Detlev	Posted - Aug 04 2018 : 12:31:35 PM The lens was used by the Stasi to take compromising photos in hotels. Therefore it was necessary to disguise the lens opening.
Luiz Paracampo	Posted - Aug 04 2018 : 11:20:47 AM Now it is clear! For optical working the front stop is unesseary it is used only for desguising purpose! Regards LP
Detlev	Posted - Aug 04 2018 : 09:52:42 AM The pinhole lens JO-1 consists of a wide angle front-stop lens and an image side telecentric lens Detlev
Detlev	Posted - Aug 03 2018 : 11:05:10 AM Here you can see the pinhole of the JO-1. Regards, Detlev , diameter 1 mm http://www.ussrphoto.com/UserContent/382018_EintrittspupillePfeil.jpg
Luiz Paracampo	Posted - Aug 03 2018 : 10:51:57 AM according to your robot pictures included it is a relay (telecentric) lens. Pierre Touzelet will have the final word. Regards LP
Luiz Paracampo	Posted - Aug 03 2018 : 10:49:49 AM all thet is true but the real pinhole, can't be seen at the diagram. so far extraordinary low apertures cant aid instant fotos. if any movement the photo will be blurred or simply unregistered what is not wanted and really useless by any spionage dept. Regards LP
Detlev	Posted - Aug 03 2018 : 10:13:28 AM Last try http://www.ussrphoto.com/UserContent/382018_Prosp_a.jpg
Luiz Paracampo	Posted - Aug 02 2018 : 7:48:31 PM see complete optical details at http://www.marcocavina.com/articoli_fotografici/zeiss_cute_dfr_ddr_lenses/00_pag_english.htm LP
Luiz Paracampo	Posted - Aug 02 2018 : 7:37:17 PM I believe to be a telecentric relay formula once pinhole has no lens at all Regards LP
Detlev	Posted - Jul 30 2018 : 3:50:14 PM The lens is a pinhole lens JO-1 http://www.ussrphoto.com/UserContent/3072018_JO-1SGk.jpg
Detlev	Posted - Jul 30 2018 : 3:20:52 PM The camera is a design of the OTS (Operativ technischer Sektor) of Stasi and not a F21 clone
Jacques M.	Posted - Jan 06 2015 : 03:10:45 AM And thanks for the site I did not know. What a mine of information about rare Zeiss lenses... Jacques.
AlexanderK	Posted - Jan 05 2015 : 5:46:26 PM Very interesting, Luiz. The camera seems to be based on F-21, but the CZJ-lens is really a masterpiece.
