So, all that being said, should you buy it? Well, do you have the need? The need for speed? If so, then you’re not going to find a faster camera out there. The A9 costs $4,500 for the body alone. While that’s cheaper than the Canon 1DX or the Nikon D5, unless you really, really need to be able to shoot fast-moving objects, then you’re probably better off with one of Sony’s A7 series cameras (get the mark II versions). These are also full-frame, mirrorless cameras that take excellent pics, they just aren’t as fast. But if you’re a budding sports photographer and you aren’t already heavily invested in glass from another manufacturer, the Sony A9 is incredible in so many ways.
