In the manual of the M5 some lenses are listed which should not be used (without mods) on a M5 because of the CdS-sensor lever. The manual was printed in 1975.
Especially from 1999 the M-System revival started and various producers except Leica offered “M” or LTM + Adapter lenses. (Voigtländer/Cosina, Zeiss, Avenon, Konica….).
Before 1972 there were a large variety of “vintage” LTM Lenses which are of course not listed in the M5 manual.
My question is which lenses not mentioned below can cause problems with the M5?
(suggestiona re V/C Heliar 2/50?, V/C Nokton 1,2/35?, new collapsible Elmar 11823 ? )
The Limit of penetration into the M5 body of the collapsible lenses is up to 13mm. (remark George S)
_ Super Angulon 3,4/21 before Nr. 2 473 251,
_ Elmarit 2,8/28 ab Nr. 2 314 921.
_ Super Angulon 4/21 LTM
_ collapsible Elmar 2.8/50 11612
_ collapsible 4,0/90 mm Elmar-M 11131 ILNOO
Not mentioned in the manual:
_ Jupiter 12 2.8/35 (caused by back lens) see remark from rxmd
