View Full Version : Rodenstock APO Enlarging Lenses
I am wondering if I will see a difference between the Rodenstock Rodagon APO 90mm f4 lens when compared to the Schneider Componon S 80mm f4 lens that I have.
Prints would be 11x14 to 16x20.
thanks.

I don't know about the APO Rodagon but the 90 Schneider HM is spectacular. It covers 6x7.

this is absolutely my favorite medium format enlarging lens, I think it is an amazing piece of glass.
It beats the hell out of all my 80mm Apo's.
the coverage is wonderful.

Yes you will see a difference. Providing you are comparing the 90mm Apo Rodagon N vs any other 90mm. But if you are comparing the old 90mm Apo Rodagon you probably would not see a difference.
To see what a lens can do you must be enlarging within the optimization range, use a glass carrier and have a properly aligned enlarger.
I am not sure how old the APO 90mm is but it has the red ring around it.

David,
If it is old it is a 90mm APO.
If it is not old it is a 90mm Apo Rodagon-N.
That is the way the lenses are marked on the barrel.
The N is much less common then the non N version. There were no "in between models" The 90mm N is a totally different lens optically and physically.
The replacement for the old 90mm Apo non-N is the 80mm Apo Rodagon N. It covers 67 wide open. The old 90mm had to be stopped down to cover a full, large size 67 (there are several different actual 67 sizes that vary depending on the camera or back you use). Additionally all Apo N lenses are multicoated,
