Canon EF 24~105mm f/3.5-5.6 IS STM. Forget the EF 24~105mm f/3.5-5.6 IS STM : it's a DSLR lens and needs an adapter to work on the mirrorless cameras. This EF DSLR lens is 50% more expensive , 35% heavier, and bigger and longer — and this is all before you add the required adapter to let it work on mirrorless cameras.
