Sigma MC-21 EF to L mount converter – does it work? I’ll show you the test results!
Richard Wong:
The Sigma MC-21 converter/adaptor allows you to use the Canon EF mount lenses on your L-Mount cameras. Autofocus, Auto exposure, EXIF are all supported but does it really work?
In this review I’ll show you the results I got after testing it with a few different EF lenses, from both Sigma and Canon.
