I went on a trip recently and was disappointed with the pics taken on my iPhone 13 (needless to say, i know nothing about cameras). Could you please recommend me a portable camera that fits some criteria:

>More megapeepees, the better.
I visit museums/galleries frequently and I want to be able to take shots from a respectful distance while still being able to read the information plaque in the final image. 12MP apparent isn't good enough.
>Be smol and light.
Every pound feels surprisingly heavy and painful when walking 5-6 hours a day sightseeing. I usually just carry water and some essentials in a small backpack when I'm out and about.
>Quick to shoot (what did i mean by this?)
Some places are extremely crowded and you only get a second or two to line up a shot. It's easy enough on a phone to pinch to the correct zoom and shoot something, but I really don't want to be fiddling with focus when there are misbehaved tourists constantly bumping into my shoulders.

Obviously cheaper is better, but my soft budget is $500 and a hard-stop at $1000. If this is an unrealistic budget given the criteria then please feel free to break it.
