Smartphone cameras are small, and that leads manufacturers to employ software tricks to improve image quality despite the inherent size limitations. You can easily find an Android phone or iPhone with a camera sporting a higher megapixel count than a mirrorless body or DSLR camera. As you’ve probably heard before, megapixels aren’t everything, and they hardly tell the entire story. Image sensor size is the more important spec than megapixel count, and that’s a problem for smartphones with tiny cameras.
