Is the sony rx100 vi better than a phone?
Short answer: it's better than a phone in the ways that matter for real photography, but only if those ways matter to you. The Sony RX100 VI has a 1-inch sensor, a built-in 9-72mm f/2.8-4.5 zoom (roughly 24-194mm on full frame), and still fits in a jacket pocket. That gives you better zoom, more light in dim rooms, and blur that comes from the lens rather than software.
If you mostly shoot daylight snapshots, your phone is probably enough. The first camera guide walks through the differences, and it's worth reading before you spend the money.
