Extension tubes must degrade quality, I would define as operating the lens outside its design intent. The only question is by how much. If kept in moderation, perhaps it is not significant.
Anyway, I fear we may be drifting off topic here. I still plan to try my proposed configuration to simulate the look of the Petzval once I got some other jobs around the home sorted. Got my box of random lens elements on standby
