What cameras are making it into peoples multi day packs? I’m not interested in you 10kg kits, it’s not a a competition. What have you found gives that quality Vs weight balance for a 5 plus day pack?
For a decade or so I have used waterproof/resistant point and shoots. Currently a Panasonic but I have had a Sony and Olympus (sadly, they are throwaway items). But I have always believed that the overall image is more important than an accurate representation of every nostril hair. One tip - if you intend to use it underwater choose mechanical selectors, not touch screens. Touch screens don't work underwater. I have this on my wall with about a metre along the long side.

I'm going through the same dilemma while planning an 8 day Tas walk. I want to take the Canon G16 at 427gm vs the waterproof Olympus TG3 at 245gm. Canon needs waterproof bag, Oly hangs around my neck. Picture quality of Canon is considerably better. Canon allows me to save power by turning off the LCD screen and using the optical viewfinder. Olympus allows me to recharge from powerbank via USB. Decisions, decisions.
I’ve got the Canon Powershot G9 X - about 4 years old now - adequate image quality-weight price ratio. It’s been superseded, but it’s in the ball park.
Olympus TG5 plus iPhone. Always have the phone but it's fragile and battery life isn't great. TG5 is very tough, I have several spare batteries (you used to be able to get spare batteries for phones, must be out of fashion).
