Rodenstock 138mm f6.5 HR Digaron SW FLOAT

[TheDude]

Rodenstock were taken over by Linos, in turn by Qioptiq who now appear to have been acquired by Excilitas, so all this may have delayed things. They do at least show an image of the 138 on their website, and the PDF says available from October 2019.

Here's the PDF (link): https://www.excelitas.com/file-download/download/public/67266?filename=HR%20Digaron%20Lenses%20brochure.pdf

Thanks. [Interesting, still showing the Apo-Macro-Sironar digital.]

The S/K has an IC of 150, the R/S's is 110. If you limit the S/K's to 110 (in order to make a comparison), then the angle of view is ~49 degrees, the R/S's is ~44 degrees. On a long lens those 5 degrees are hardly noticeable. Outside of highly specialist applications, I don't see any situation where you would reach for the R/S instead of the S/K (if you had both), unless you're a masochist and enjoy the workout of lugging a heavy lens any distance, and the jeopardy of dropping the behemoth.
