■ To be frank, camera autofocus has many more pros than cons, and any minuses are more annoying niggles than actual faults. Having kit capable of focusing on fast-moving subjects in near-darkness or to lock on someone’s eyes is a wonderful thing. Just learn to recognise when AF can trip up, and practise to remedy any issues.
✔ Eye-tracking
Eye-detect AF works well on humans, birds and animals, although it can trip up in low lighting or with dark subjects. Many AF systems offer the option of left- or right-eye priority; in most situations, set Auto and let the camera decide.
