Does that lens suffer field curvature due to the sensor stack?
It would probably be best corrected by the 10m eksma optics if anything. @HaruhikoT will chime in if they get a chance. You could definitely help by measuring the exit pupil.

Hi everyone,
I am late to the party but I am extremely interested in this solution. I have a Voigtlander 50mm f1.5 and I am wondering if the Opto Sigma SLB-50-5000PM is the best solution?
