Is the sony rx100 ii better than a phone?
The Sony RX100 II is better than a phone at some things. Its 1-inch sensor gathers more light, so indoor and night shots tend to stay sharper. Its built-in 10-37mm lens frames like 28-100mm on full frame, and the fast aperture gives real background blur that a phone can only fake.
It dates from 2013, though. If you want the same idea in a newer body, the Sony RX100 VI is also in the catalogue, and the Sony RX100 V sits between them.
Whether it's worth carrying depends on what you shoot. Read what a camera does better than a phone to see if those strengths matter to you. If daylight snaps are enough, your phone is fine.
