OK

pu2. mk3 -> mk4 : 4K Introduction, mk4 -> mk5 : Af Speed Improvement

OK

pu3. If you want to film something moving fast, mk5 is good. In particular, mk5 is good when moving fast when there is not enough light, such as indoors. You don't need that function. If you're going to take pictures of scenery and people, mk4 is enough
