With the philosophy that bigger pixels make a better picture, Apple has replaced the 8-megapixel main camera sensor of prior models with an 8-megapixel camera with 1.5 micron pixels. It kept its great optics and software. HTC's camera pixels are even bigger, but there are less of them. The M8's camera offers 4.1 million pixels that are 2.0 microns in size. HTC also claims that dual sensors in its camera allow it to refocus an image after it's been captured. Sensors in both devices spread their pixels across a third of an inch. Apple's aperture is f2.2; HTC's is f2.0. Both companies claim to capture 1,080p video at 30 fps.
