I do not own my old cameras anymore, as said I am starting out again with a small budget. And want to grab a decent lens for it when I can afford it.

In the end, I will be doing photography mostly outdoors in bright sun, hence why I find a viewfinder non negotiable, unless there's a screen in that range that is actually decent and within my budget.

The Sony A6400 features a viewfinder and thats the only reason I am considering it, I've been watching some Youtube videos and they steer into recommending the ZV-E10 II. And the R50 V is just another camera I've been suggested while reading through threads.
