...there is an obvious loss in image quality when the tube lens is focused too much closer than infinity. Note that the importance of this aspect depends strongly on the NA of the objective. Narrow aperture objectives such as NA 0.25 have a lot of tolerance, wide aperture such as NA 0.55 have much ...

There's nothing in there to suggest that if you don't need the accessories, you still need the space.--Rik Rick, that is exactly what I wondered alll the time. We see your very nice an clean pictorial results (putting the NIkon 10x/0,25 JUST with only minimal distance in front of the "tube lens") -...

Rick, sorry for that, I did not read it properly... Thankyou for pointing to this again!

I think that the consensus on the direction of the 75mm f4.5 2X Apo Rodagon D lens on the forum is based upon testing of the lenses in both directions and viewing the results for sharpness. ...Rich Rich, of course you are right, concerning the test-results... On the other hand, for the ease of use ...

Hi all, about the use of the Rodagon-D lenses, so far the official pages do not recommend a special reversed use: http://www.linos.com/pages/mediabase/original/rodenstock_apo-rodagon-d_dt_2005.pdf english here (page 17) http://www.darkroom.ru/info/manuals/rodenstock_enlargering_lenses_manual_eng.pdf...

In "retrevial of the honour" of the famous EL-Apo-Nikkor, we have to bear in mind, that this lenses APO-Enlargaing lenses 105 mm /210 mm and 300 mm once had been designed - long ago - for a frame-coverage of at least 6x7 cm up to 8x10". Therefore, as the Printing-Nikkor is a 1:1 copy-lens for 35 mm ...

Ray, thankyou very much for this comparison and the work you had with it...! That the Printing-Nikkor 105mm is a league itself is clearly shown, in my opinon. The last auction-price for this should be explained with the poor condition of the offered item... Again, the performance of the Rodenstock l...

Dear Ray,

thankyou for your work on the second test! Again, great to see the power of the Rodenstock/Scitex lens, how plays on its own. Finally, if you really can throw in the "normal" other Apo Rodenstocks, as offered, I am very curios on this expanded results...!

Best wishes,
christian

Ray, thankyou for the first part -- I am suprised and pleased with the result of the Rodenstock S-3 5/100 mm in this range, I never would have believed, that it outperforms the famous APO-EL-Nikkor...!
thankyou for further parts...!
regards,
christian

...I started a thread a while back asking that question. But so far I've seen no responses with anything that is better, or even as good, as the PN's. Ray, could you show a comparison of Printing Nikkor 2,8/105 mm vs. APO-EL-Nikkor 5,6/105 mm and the Rodenstock/Scitex 110 mm/ 5.0 This EL-Apo-Nikkor...

... I assume this since the Macro Nikkors are either M39 or RMS, and have specialized adapters to mount them to Nikon F mount. The adapters are the BR15 (F male to M39 female) ... Ray, if you have these BR-15 adapters - they are highly appreciated for collectors. Now there are many (Chinese) Adapte...

Nikon still produce this lens(es), now labeled as "rayfact" -- I believe still only available in Japan, list price for the 105 mm (=OFM 10090MN) I read some times ago about a list prize round 3000.- USD (??) for the 105mm http://www.tochigi-nikon.co.jp/products/lens/raysensor.pdf Also the famous Nik...

Harold, as far as I watched this auction, I think it is at least the third time now, that the seller pushs it (I do not know, why it came back 2 times ?) the specific famous Japanese collectors link is: http://homepage2.nifty.com/akiyanroom/redbook-e/repro/printing105.html the 150 mm version - " Hai...

Rogelio, your pictures are really great! :lol: As for your setup - beside the perfect Nikon TE300 microscope - you use flash in addition. Can you - please - show us your setup and HOW you place/use the flash? Betwwen subjekt and halogen-source (with use of a beamsplitter) or - because of enough "spa...

Craig, I had a Nikon D70 - converted for infrared (converted in Germany) - as far as I know, this 6 MP camera was best suited for this, now I have a D200 converted, but I have to try again, I played around with black-and-white, this including channel-shifting - which brings for me - for my taste and...
