Rich, thanks for your work!
May I point out that a vintage collapsable Elmar 90mm/4 when fully collapsed, the tube will extend past the lens mount exactly 20.5 mm, just the limit stated by Epson. But on my rd1s, after mounting this collapsable Elmar 90mm, when I tried to collapse it, something block the lens tube after it has collapsed for about 6-7mm.
