Rodenstock Technika Sironar 150mm 5.6

[mazurkorn]

It is my first post so i would like to say hello to everyone of you :)

I am looking for info about Rodenstock Technika Sironar 150mm 5.6 lens - I could not find any on the internet. Is it any good, will it cover 6x17?
I have an opportunity to buy this in a good price I believe.

This site has considerable information. To see the FAQs and articles, click on "LF HOME PAGE" at the upper left corner of the screen. It also has a source that's harder to find. The first post in this https://www.largeformatphotography.info/forum/showthread.php?138978-Where-to-look-for-information-on-LF-(mainly)-lenses has a link to a pdf list of links to sources of information that may be useful.

Large format helps those who help themselves. I can't believe you couldn't find anything about Rodenstock lenses on the 'net. Catalogs and articles about them are less common than recipes and pictures of kittens, but they're there.

Maybe the Technika part is throwing you. The lens is a Rodenstock Sironar (precursor to the N and S models) which was tested and "selected" by Linhof as good enough for Technika camera use. It should cover 6x17 but with less wiggle room than the later N and S models. Some Sironars of the plain Sironar (not S or N) era have been known to have separation problems due to the new synthetic cements being tried. Check for this.

If you google "Rodenstock lens serial numbers" you'll see this lens was made around 1966-1969.
The "original" model Sironar was convertible but I see only one f/ scale on this one. Maybe there's another around the other side? Maybe someone who knows more than I can add something here.

Thank you guys! Surely, I was able to find info about Rodenstock lenses but, as Chauncey pointed out, I was misled by 'Technika' inscription on the lens.
