Do Camera Sensor Sizes Matter?
One of the headline specs of any camera -- whether it's a point-and-shoot, mirrorless model or even a smartphone camera -- is the size of the image sensor. It's clear in the marketing that a bigger image sensor is better, but why? Does a small increase in sensor size really make that much of a difference? Should you, when looking for a new camera or phone, consider sensor size?
The truth is, maybe. In certain situations, a larger image sensor can have significant advantages over a smaller sensor, but the specifics matter. Different lenses, technologies such as pixel binning and advanced computational image-processing techniques can all help smaller sensors perform more like larger ones. Also, depending on what kind of photos you're taking, it might not matter at all. Here's why.
The basics
An image sensor is a device that absorbs light and converts it into electrical signals that...
