Personally I've just stuck my camera in whatever purse/bag I was carrying around in Europe. I picked whichever lens I wanted for the day and didn't bother bringing a second. I did that because the camera bag I usually use at home was too big for what I felt like carrying around. It was the older version of this https://a.co/d/0cHzJgKc though I'm not sure the current version is current? Didn't look too hard. Very much like it as the padded part can hold a camera and at least one extra lens, several outer pockets with one that can hold a water bottle, and roomy inside that's expandable. I took it on my Alaska cruise, but I knew I'd be switching lenses way more there.
