So I would like to upgrade from my SONY A7R3 to A7R5, but I can't justify $4600 for a new housing. I'm very happy with my current Sea and Sea housing, ports, etc. So I wonder if there is anyone out there in SB land that has tried to mod their existing housing for a new camera with slightly different dimensions? Seems like a reasonable task for a MacGiver type with the right tools, possibly even a lucrative, recurring side hustle.
