Canon is used to setting trends, not following them. But the popularity of mirrorless camera technology has the world’s leading camera maker playing catch-up in a race that was started nearly a decade ago with Epson’s R-D1.
That can't be right. I've never heard of Sony using BSI image sensors. They only appear in some compacts and mobile phone cameras like the iPhone. BSI APS-C? that has to be an error. As for Canon, it looks like more of the same, stuck in the same place for the past 5-6 years, their APS-C sensors need a major overhaul. It's sad that a used Sony NEX C3 has an image sensor that beats the one in a Canon 7D.
