Rodenstock APO Geragon

I know the Geragons are process lenses optimized for 1:1 at small apertures. Has anyone been using one for enlarging? If so, besides the small aperture wide-open and stopped down for printing, how well do they do, or do they not work for enlarging at all?

Thank you.

It's pretty clear that Beseler used a rebranded 240/9 Apo-Gerogon as the lens on the 810 conversion kit as it would clear the mechanical restrictions behind the lens board (unlike a 240 Rodagon) - I recall it's somewhere around a similar size to a 150/ 180 Rodagon - and the same thread.

Yes, similar size to the 150/180 and the same thread.

I haven't printed with mine yet but the projected image is nice and all corners are sharp. A little bit after I got mine I bought a Rodagon 240. I'll have to compare the two at some point.
