In manual, a LiDAR Waveform display gives a 3D map view that’s from an imaginary top-down position. So, you can use the focus knob on the camera’s right handle to quickly and accurately move the focus point to a precise part of the scene. Implementing autofocus keeps a sharp lock on the subject, and it works well, even with a fast prime lens wide open – especially with face detection.

The LiDAR continuously fires out 43,000 laser measurements to help precise focusing, even in really low light. It doesn’t rely on surface textures or edges, so offers a blisteringly fast focus speed. But this only has a range of ten metres, so again, not ideal for longer lenses. If the sensor had phase
