|With 1mm extension, lens cannot focus to infinity.
For M42 Takumars:
15mm, I don't know.
17mm fisheye, EOS FF mirror clears.
20mm, EOS FF mirror hits when lens focus is set to infinity, sometimes.
24mm, EOS FF mirror hits.
50mm, EOS FF mirror hits when lens focus is set to infinity, sometimes.
No problem with longer focal lengths.
