I don’t have experience with the TAMRON, but those other two lenses are pretty mid. I’d sell them and get one interesting prime like a 35 or 50 Zeiss classic (or even an adapted contax yaschica) for the 5d.

Had them both and used them a bit but moved on.

Manual focus with a flashlight if you have a subject within 50 or so feet. Otherwise manual focus to infinity and cross your fingers.

Hasselblad h6d with the 150mp back. You won’t regret it.

You might need a bike trailer though.
