Sony recently unveiled a smartphone camera sensor with the highest resolution yet, a jaw-dropping 48 megapixels. That's more than the resolution of its $3,000, 42.4-megapixel A7R III mirrorless camera, which has a sensor eight times larger. It sounds great, but you might have forgotten that Nokia's 808 PureView smartphone, with a 41-megapixel camera, was released way, way back in 2012. Why didn't modern smartphone cameras follow Nokia's lead?
As Apple has demonstrated over the years, from the iPhone 4s and forward, you get more benefits with other features, like dual cameras and sensors with bigger, more light-sensitive pixels. Those deliver better low-light shooting, more bokeh, faster speeds, zoom capabilities and improved video. However, Sony now believes you can have all that and high resolutions, too. Its Quad Bayer tech, reportedly used in Huawei's P20 Pro camera, might help big-number megapixels make a comeback -- and this time, they'll be far more useful.
