Can the lenses of the Canon L line be adapted? Like the 24-105mm II and the 85mm 1.4?
Asked by: Isaac
I contacted Sigma directly because I own a number of Canon "L" lenses and a Leica CL. Below is the response from Sigma: Thank you for contacting Sigma USA. Our MC-21 is designed for Sigma Art, Sport, and Contemporary lenses only. Unfortunately the MC-21 will not work with any of the current Leica cameras, but will with future models.
