I recently acquired several “vintage “enlarging lenses,all used of course, and with some time on my hands I decided to do an informal test after I noticed one of my 8 X 10 prints looked out of focus on the edges. The lenses in question are :
1. F 2.8 50mm El Nikkor,
2. F4 50mm El Nikkor.
3. F 4.5 50mm Wollensak
4. F 4.5 75mm Wollensak
5. F 4.5 75MM Schneider-Kreuznach Componar
6. F 4.5 50mm Kodak Projection Ektar
The 2.8 El Nikkor should be the star of the group as it is a 6 element lens. The Ektar has 5 elements with a Heliar design from 1945. The others being a tessar design and a triplet in the case of the Componar( an inexpensive 4 blade diaphragm). The Wollensaks were heavy precision stainless steel with the “W” logo in purple(lens coating?) probably made in the 60’s. The two El Nikkors were probably made in the 70’s, 80’s or 90’s. My tests were very informal and modest… just used several of my negatives that had lot of branches and buildings with windows, etc. My enlargements were all 8 X 10. My tests were mostly to test edge sharpness as all 6 lenses were tack sharp in the center. The 50mm lenses were tested on 35mm film and the 75mm lenses were tested on 120 film.
The biggest surprise was that the 2.8 El Nikkor was not that good, especially at the wider apertures on the edge... it really didn’t get ok until F 5.6 and was excellent at F 8 and F 11. I was led to believe that the attraction of this lens was that you could expose prints at the widest apertures and that it would maintain the sharpness thru all apertures. The F4 EL Nikkor also was disappointing at F 5.6 and F 8. It was rated Good to VG at F 11.
The Kodak Projection Ektar was VG at F.56(One stop from being open) and excellent in all subsequent stops.
The Wollensaks really surprised me too, as they have a so so reputation based on reading many forums. The 50mm lens was even good wide open. All other stops were excellent. The 75mm Wollensak was excellent from F 5.6 through F 16.
The 75mm Schneider Componar did not disappoint either as I expected mediocre results from this triplet. It was however excellent from F 5.6 thru F 16.
Again my tests were quite modest and were only 8 X 10’s. The El Nikkors could have been lemons… the 2.8 lens had very slight swirl internally in the rear element but it was really faint that is only detected with a strong light and I do not think it impacted on the results but I could be wrong. The Wollensaks and the Kodak Ektar are real gems and bordering on antique!! Go figure! The cheap Componar that I got for $2 in a thrift store was pretty amazing too.
Those are my meager results but others may have had different outcomes.
