I love my Sony 2600 mirrorless, and it goes on all trips, but doesn’t have gps. So I also snap a couple of photos on the phone for mapping location (eliminates the need for travel notes) and also for quick social media posts or messages to family with a photo.
Also, for night photos, I don’t tend to have a tripod with me so, I find my iPhone 13 does great night shots without a lot of fuss.
