Last month, Sony introduced its A6300 mirrorless camera, a follow-up to the sought-after A6000 from 2014. As expected, the company's latest compact Alpha shooter brings top-of-the-line specifications. That includes a 24.2-megapixel APS-C sensor, a Bionz X image processor, 11-fps continuous shooting, ISO up to 52,000 and 4K video in Super 35mm. In particular, Sony is emphasizing the A6300's newly developed 4D Focus, which is capable of locking in on a subject in a ridiculous 0.05 seconds. That's speedier than basically every other camera available right now.
