300mm f/9 Rodenstock Apo-Ronar soft image

[felix_ackermann]

well - I read this thread wondering about some quite arrogant statements (who needs this, needs it ...).

 

Myself I know that I could never use the very small apertures of my Apo Ronars for photography; but I suspected that there must be a use for "f/260"...

 

Therefor I adressed the question to a 71 years old, very experienced repro photographer who explained it to me.

 

(I hope I can translate it into understandable english...)

 

The small apertures were used for the pre-exposure (one of three; all with different apertures) for glass rasters.

 

He wrote me a whole instruction in German - I could transmit it to whom it may concern...

<p>I just picked up a Rodenstock APO-Ronar 300mm 12in without a shutter. I am new to this so can anyone tell me what shutter I need to find for this baby?<br>

thanks,<br>

<p>Copal 3 + the required aperture scales.</p>

<p>It may not be as easy as unscrewing the cells from the barrel and screwing them into the shutter. Some barrel-mount Apo-Ronars have different threads from the shutter versions. You can figure out from the thread dimensions given in the table at S. K. Grimes: http://www.skgrimes.com/products/index.htm</p>

<p>digging a dead horse. Would this lens work as an enlarger lens for printing?</p>

[bob_salomon]

No. It is a process lens designed for copying flat objects, like a print, at 1:1 or near 1:1 at f22 only.

 

Rode stocks enlarging lenses are/were the Rodagon, Rodagon G/ Apo Rodagon (up to 180mm only), Rogoar, Roganr S,

etc.
