How to get better autofocus June 23, 2021 Mirrorless cameras have introduced a range of new autofocus systems, so Angela Nicholson explains the good, the average and the downright amazing As mirrorless cameras don’t have a mirror to bounce light into a viewfinder or onto a dedicated autofocus sensor, they use the imaging sensor to gather the focusing information to drive the lens. The first mirrorless cameras used contrast detection autofocusing, and although some manufacturers have stuck with it, most use phase detection or a hybrid system that combines phase and contrast detection. Contrast detection is a very accurate method that looks at the edges of the subject and moves the focus until the point of highest contrast is found. Its problem is that the camera has no way of knowing which direction to adjust the focus initially, so it can go the wrong way.
