Sony has just launched its most impressive, and most expensive mirrorless camera yet, the 24.2-megapixel Alpha A9. Equipped with the first ever full-frame stacked CMOS sensor, it's all about speed, not resolution. The pixel count isn't that high compared to the 42.4-megapixel Alpha 7R II, but it can shoot up to 241 RAW, full-frame images at a scorching 20 fps, thanks to a processing speed 20 times faster than previous models. It also has an ultra-dense 693-point focal plane phase detection autofocus that can do 60 AF/AE tracking calculations per second.
