Sony Alpha 58 review – Autofocus
Image: The Alpha 58 has 15 picture effect filters that can be applied to images, though only when shooting JPEGs
The Alpha 58’s AF performance is good for a camera in this class, with speedy AF most of the time, especially using one of the three cross-type points, only hunting in low-contrast situations. One niggle is the grouping of the AF points, seeing a bias towards the centre of the frame, which often results in the need to focus and then recompose if the subject is positioned towards the edge of the frame.
The Alpha 58’s SLT technology means it is able to utilise its 15-point phase-detection AF system during live view and video recording, rather than having to rely on slower contrast-detect AF as most DSLRs do. It therefore delivers the same level of performance via live view as it does when using the viewfinder.
