Blink and you'll miss it: the new Sony A6300 and three G-Master lenses 0.05 seconds, or 50 milliseconds, is not a lot of time at all. It's about the same time that small, frantic birds like finches take to beat their wing. Comparatively, a human eye takes ages to blink: the average double wink takes 300ms to complete.

The new Sony A6300 can snap to focus in just 0.05 seconds - a new autofocus world record for a mirrorless camera with an APS-C sensor.

Let's put this into perspective. Recent research suggests that the human brain only needs 13ms to ''see'' something and recognise it. A muscle movement, such as your brain telling your arm to lift the camera to your eye, takes just 200ms to execute. So if you owned this new mirrorless marvel from Sony, it's entirely possible that you could spot a fantastic photo, decide to take a picture, raise the camera, snap to focus and capture your shot - all within just one second. That really is fast.

The 24MP Sony A6300 is the long-awaited successor to the A6000, and it's a proper update: Sony has gone to town on reworking the speed, imaging and processing power hidden within this compact body.

The standout feature is called 4D Focus. The Sony A600 had 179 points of focus: the new A6300 has an astonishing 425 phase-detection focus points, distributed evenly across the whole of the camera's APS-C Exmor CMOS copper-wired sensor. So even if your subject ends up close to the edge of your frame, you'll still be able to lock onto your target.

And if that target starts to run, Sony's ready for it. A top speed of 11fps means you're unlikely to miss a moment - and Sony's High Density Tracking feature claims that the AF will intelligently respond to the movement of a subject by readying the focus points nearest your target as it moves across your frame.

One of the most exciting features is the A6300's ability to capture up to 8fps while you're using Live View on the camera's rear screen. In the past, mirrorless models shooting at high speed tend to give a sort of staccato-style intermittent viewing experience, making it tricky to keep your subject in frame - but the A6300 changes all that. You'll still see the occasional black frame while the camera resets, but it's astonishingly impressive.

If you're more of a viewfinder-type person, the XGA OLED Tru-Finder on Sony's new offering is excellent. You can also switch the viewfinder up to 120fps for beautifully smooth visuals of the scene before you.

And if you're more into video, there's plenty here to keep you occupied: 4K capture with Super 35mm format, a dedicated microphone line-in, plus Full HD at 120 fps at 100 Mbps - which is another first for Sony's cameras with APS-C sized sensors, Low-light video quality also promises to be impressive - and all that AF technology also applies to movie capture.
