I use it with enlarging/repro lenses, Rodagon 105 and 135 and Apo-Gerogon 150. Those work great as "relay" lenses in my experience.RobertOToole wrote: Thanks for the idea Macrero.
I was going to reply that I had given up on stacking combos, I tried maybe 6 pairs recently and all I found was sharp centers but all bad corners and lots of CAs.
But your message gave me an idea. I do have a 28/2 Xenon that beat the Componon 28s (3 types) and the 35/2.8 at 4x. That might work.
The Sigma 150 macro would give me a little over 5x.
I stop down the reversed lens, in my tests that works better than f/stop between the lenses, but it depends on the optics you use, so it is always good to try every possible configuration.
