Yes, 47 60 29.
Thank you very much for the link! It also links to
http://www.mikroskopie-forum.de/index.p ... #msg120059 very interesting
I have not at hand comparable tests and I don't have the expensive S-Kpl, I only have 10X Kpl and 8x Kpl and in fact have not done intensive tests with them as I mostly use Leitz objectives and eyepieces, but I have never seen this amount of CA with well matched good objectives and eyepieces, both Zeiss or Leitz. Time ago I tested the 63mm lens against a Olympus 50mm 1.8 afocally and I'd find the results about the same, magnifcation aside.
Used alone as camera taking lens 47 60 29 is very poor while the Oly is very good but they are not designed to do the same. In a different but to some extent comparable situation Rik, IIRC, posted a test of different tube lenses for infinite objectives and tested the winner, a Raynox close-up doublet as taking lens: unsurprisingly it was poor for that job, so likely only real life tests will end to be significative
After this most interesting discussion I've added redoing the tests in a careful way to my long to do list, but likely it not in the short term.
