The One is a pricey iPhone accessory — it's nearly as much as the phone itself! — but it's also a solid option if you're looking for a portable way to get much nicer photos than you'd typically get on your phone. Inside the One is a 1-inch sensor, which is the same size sensor you'll find in higher-end point-and-shoots. It's able to stay so much smaller and cheaper than those cameras by leaning on the iPhone for various functions: it plugs in through the Lightning port and launches a specific shooting app, and from there you can take photos and videos and even set manual controls.
