Concentrate you autism here and leave the other threads alone.
Also I'm disguising a personal question thread as a general because /gear/ never replies with relevant information.

Basically, I want to upgrade to a body and lens system that is capable of professional work.
Currently I have a 7 year old M4/3 body and 4 subpar lenses for it, and I don't feel like getting more lenses since the cost would be very similar to equivalent FF lenses.
After some thinking, I've set my budget at a cost of a A7IV for the body, and for lenses I haven't decided for sure yet but I know I'll need a 70-200 first, either a new Tamron or used Sony.
Now more importantly, here is the list for the kind of photography that I can start doing.

>Sports (Soccer, Football, Tennis, Indoor basketball & volleyball, Boxing)
>Events (Theater, Car shows, Art expositons, Community, School)
>Portraits (Personal, Corporate, Fashion)
>Wildlife (Birds, Snakes, Wild game)

So will the A7IV with appropriate lenses be able to cover most of that list or am I better off bending over to a different brand that's at a similar price?
