Specs for 300mm Rodagon-G Enl. Lens?

[neil poulsen]

What is the optimum enlargement factor for a Rodenstock 300mm Rodagon-G f5.6 Multicoated enlarging lens? For example, what's the optimum print size using this lens to which I could enlarge an 8x10 negative? I know they can print large; but, how large?

What tends to be the optimum aperture for this lens?

What's the image circle of this lens? (e.g. the largest negative that it can print?)

and I believe I have paper poster shot on 35mm so well enlarged with detail only a G Rodagon could have made it

I sent the handheld Leica III neg to a mail order outfit, $6.95 delivered in a tube

Made 1987 and hangs in the next room under old plastic

I have Digi copied it and posted here long ago, now deleted

G Whiz!

Woe, talk about days past.

Sounds like I have a relic.

We had a thread on the Coloramas, with a bit of insight and a lot of noise:

Still would be interesting to have a more detailed account of exactly how lenses like the longer Rodagon G series have been used.
