I often use the 150 Apo Rodagon N for medium format enlargements. Of course, it will handle 4x5 too, but with a bit of illumination falloff toward the corners unless you have an exceptionally effective mirror box above it, or properly ground diffuser. In either case, the performance is conspicuously better than what any 135 will achieve. But I have plenty of headroom with my Durst floor to ceiling columns.
I already stated earlier that my ideal of "normal" for 4x5 is actually my 180 Rodagon, since there is no falloff. But I've even used my 240 Apo Nikkor, which is optically the pick of the litter. I did use a 135 Rodagon back when all I had was an old Chromega D enlarger and needed to make 20X24 color prints. It was decent.
A very nice looking 150mm Componon S arrived today but the threads are 42mm and the El Nikkor's lens board hole is 39mm. No 42mm hole board with the illuminator on ebay so I ordered a 25mm hole lens board and a new hole saw. I used the old hole saw on a 4x4 piece of heavy sheet steel which I painted black and is drying in the shop. The hole saw was on it's last legs but did make the hole which I cleaned uo with a die grinder. That should get me printing until the new lens board arrives. I have a miniature flashlight I can use to see apertures until the board with a light pipe arrives. The darn lens has half stop clicks and I'm going to have to check for a while. lol
Gotta love analog, can't fix digital with machine tools.
Anything digital is easy to fix once for all with a heavy pipe wrench. All of it ends up flattened as e-waste sooner or later anyway - mostly sooner.
So that's how it is. Schneider and Nikon have the aperture close in Opposite Directions. Bet that's where Apple and Microsoft got their cues. Just do the opposite. Buggers! lol
Ya but they manage to have their engines run in the same direction.
The Componon S appears to be a hair sharper than the older El Nikkor but more noticeable is the increased contrast. Also the El Nikkor needed 1/3 more exposure at the same f stop. I printed on fiber and will check with a loop after the prints dry.
I managed to find info on the Componon S I bought. Its design is from about 1986. Magnification range 2-20X and they claim an ultra flat field and superior color correction.
