Kooka extension tube set for EOS M lens mount_Mamiya 6 but focusing is accurate and"Kooka" is not a brand we've ever seen before, but this is a pretty decent generic extension tube set for the Canon EOS M mirrorless system. Extension tubes provide additional lens extension for macro photography (lens is not included.) In excellent condition. This is for the Canon EOS M mirrorless system, not the normal EOS or EOS R systems.
