I have a canon efs lens that I use with my 40d. I also have a lumix gx7 and canon eos m, both mirrorless. The lumix has a m43 sensor and the eos m has a similar sized sensor to the 40d I'm 99% sure.

Would there be any benefit to adapting this lens to the eos-m than the lumix gx7 because the eos-m has a similar sized sensor to the 40d?

Forgive my lack of knowledge, I'm decently knowledgeable otherwise of photography in general.
