I just got a SIGMA 17-70 1:2:8-4 DC (C) lense. Mount looks very much like Canon EF (S) but it's smaller. Added a foto from a 70-200 EF to compare. Anybody knows what this mount is for? Many thanks in advance

Thanks @Nate S. for his answer.

This looks like the same thing, so yes, SA: https://www.worthpoint.com/worthopedia/sigma-17-70mm-2-4-macro-dc-sigma-sa-1791976047

Solution is Sigma SA Mount

  • Sigma SA reportedly uses the same communication protocol as Canon EF, which explains why it looks like an EF mount from an alternate universe. – xiota Feb 4 at 3:48
  • IIRC you have have the mount changed by Sigma service. Nice lens, that's my "standard" one. Just a bit soft at 17mm. – xenoid Feb 4 at 10:25
