    Apo Rodagon 2.8 50mm

    Dear all,

    Not being a specialist in this matter, and not that is matters too much, now using a Nikon 50mm 2.8, only curious...

    I purchased another M805 and with the enlarger there is also the apo rodagon 2.8 50mm (not the recent N version) enlarger lens.

    How do you judge this lens comparing with the Nikon??

    Many thanks!
    Fred

    It's probably a better lens, but you have both of them in hand, so you tell us!

    I have a 50/2.8 Apo-Rodagon, and I think it's sharper than the Componon-S that it replaced.

    I use this lens , for all my 35mm work , I have 5 of them and I cannot tell the difference between . I also have a 2.8 schneider and find it not being used . I am very comfortable with all the apo rodagon lenses in their different formats and these are the lenses I use .

    I've been using a Rodagon APO 50 for a short period of time and I must admit something was alittle "off" with my prints. So the other night I made an 8x10 print from a negative with detail throughout and grain was evident, left everything setup and changed enlarging lenses only. I went from the Rodagon APO to an El-Nikkor 50 2.8. I used 5.6 on both lenses and found the El-Nikkor passed more light so I had to cut exposure time from 14 seconds to 10 seconds to match print density. I also discovered the print from the El-Nikkor is noticeably sharper than the print from the Rodagon APO!! The grain and detail is crisp in the Nikkor print and the grain and detail in the print from the Rodagon isn't quite there. Having the prints side by side makes the difference very obvious. I'm surprised by the results.

    Regarding the above test

    Are using a glass carrier?
    Did you grain focus between mounting of the second lens??
    Are both apetures the same?

    I have both lenses you speak of and my observations are completely different re: sharpness.

    I've seen many claims that the sample-to-sample variation within single enlarging lens models is greater than the difference between high-quality models. Thus, it's entirely possible that br549 simply has a good Nikon and a poor Rodagon, whereas Bob's got a good Rodagon and a poor Nikon.

    I used a borrowed Apo Rodagon and it was very sharp, but the prints lacked a certain look that the Schneider and Leica enlarging lenses give.

    My all time favorite is the second version 4.5 Focotar with the large front element. The first version is somewhat of a dog larger than 7x mag. The very last Focotar 2 is sharp with the Leica look, but the field is not as flat as the Schneider designed version two requiring some stopping down. The middle version can be used fully open.

    At one point I tested a 100mm Schneider against the rare 100mm Focotar 2. They were very close if not identical.

    When I ran the test I did not use a glass carrier. The aperture was f5.6 on both lenses and I did a careful focus check prior to making each print. To confirm what I found I used the Nikkor and made prints from negatives I'd recently printed with the Rodagon and the Nikkor prints had the bite the Rodagon prints did not have. The difference isn't obvious unless the prints are placed side by side. I was very surprised by the results given the reputation of the Rodagon.
