Compact Cameras

A Compact Camera builds the lens into the body and gives up any mount. Two very different tiers hide under the same name. The cheap tier uses a 1/2.3 inch sensor of roughly 28 square millimeters, which a current phone beats in almost every light. The tier worth buying uses a 1 inch type sensor at 13.2 by 8.8 mm, about 116 square millimeters, behind a zoom that opens to f/1.8 at the wide end. That pairing fits a jacket pocket at around 300 g and 40 mm deep.

Next to a Mirrorless Camera the compact loses two stops of light and any way to change perspective, then wins on the days you actually have it with you. Bridge Cameras use the same class of small sensor with vastly more zoom in a body ten times the size. Action Cameras beat it for water and mounting while fixing you at an ultrawide view. Against a phone, a premium compact wins on zoom that comes from glass rather than cropping, on dials you can turn without looking, and on files that survive heavy editing.

It suits travel where a bag is unwelcome, street shooting where a large body changes how people behave, and anyone who wants a second camera living permanently in a coat. Parents and hikers get something that survives a pocket. Skip the class if you need long reach, shoot indoor sport, or already carry a phone with a real telephoto, because a 1/2.3 inch compact adds nothing at all. Remember too that a fixed lens means one jammed zoom motor or one scratched front element ends the entire camera rather than one component.

Read the aperture at both ends of the zoom instead of the wide end alone. F/1.8 to f/2.8 is a usable lens in poor light, while f/3.5 to f/6.3 is a daylight lens whatever sensor sits behind it. Look for a built in neutral density filter if you shoot video, and a viewfinder if you shoot in sun, since a rear screen at 500 nits vanishes at noon. Retracting barrels draw in grit, so keep the camera in a small case rather than loose beside keys and sand.
