Adapting basics#
A lens can be adapted with simple tube spacers when its flange distance is longer than the camera's. With 20.00 mm, Canon RF lenses can in principle go on bodies with shorter flanges such as Hasselblad XCD, Sony E-mount, Canon EF-M, Fujifilm X-mount, C-mount, Nikon 1 (CX). Bodies with this mount can take lenses from longer-flange systems such as Samsung NX, Fujifilm G-mount, Pentax Auto 110, Chaika, Leica M, M39 / LTM (Leica thread), Olympus PEN F, Contax G.
