![]() ![]() Lens quality varies between phone cameras and can make a huge difference in how the photo turns out. When you switch to the wide-angle option on your phone's camera app, for example, you'll really be switching cameras. Lens options vary, but the best cameras often have one standard lens (generally referred to as the "main camera"), one wide-angle lens, and one telephoto lens for getting closer images of distant subjects. Technically, each one of these lenses is a separate camera, but they're all controlled together via one camera app. The majority of camera phones feature a multi-lens camera setup this applies even to fairly basic models. That said, sensor size and quality are only part of the larger picture. Because smartphones are compact, they don't have sensors anywhere near as big as DSLR cameras - the largest phone camera sensor measures 1 inch across the diagonal (though between 0.4 and 0.8 inches is more common), whereas DSLR sensors approach 1.4 inches across the diagonal. The smaller a sensor is, the more the image quality will be compromised, so bigger is better. This makes it among the most important factors influencing image quality. In simple terms, a camera's sensor is what takes the information from the light entering through the lens and transforms it into an image. This doesn't mean you should ignore the number of megapixels a phone camera offers, but it shouldn't be the only factor you consider. A 12MP camera with a top-notch sensor and lens could produce better-quality images than a 48MP camera with a subpar sensor and lens.Īt the time of this writing, the highest megapixel camera packs a whopping 108MP punch, but photos taken with a camera with 48MP or more are generally downgraded to take lower-quality images via a technique called "pixel-binning" unless the lighting conditions are perfect. Megapixels are often used as a way to compare the relative quality of cameras, with higher numbers of megapixels generally considered superior. Some aren't obvious at first, so you could be missing out on some cool functions. Take time to familiarize yourself with your phone's camera and all of its various features.
