Yeah, I wanna Weather sealing. To be honest it's kinde pathetic - You will gonna pay big pile of cash for one of the latest product and, they don't even bother to trying to protect it.
It makes me feel like Sony wanna cut few things even if they should be BASIC in 2019, and save few bucks, lowering overall quality of their product.
Later, as customer especially after warranty: Water? Sand? etc. This will be your problem.
