Which camera should I buy for travel?
For travel, I'd start with the Travel guide's rule: one camera that's good at everything and light enough to carry on day five. Two bodies on this site fit that brief.
The Panasonic Lumix S9 is the one I'd pick if you want full-frame image quality in a tiny body. It has no viewfinder, so you'll be composing on the screen.
The Fujifilm X-M5 is Fujifilm's smallest and cheapest X body. It's also viewfinder-free and aimed at video and travel, so it's a good pick if you want the lightest kit.
If you're new to this, Your first camera explains when a phone stops being enough.
